For some reason it cut a minute out of the video around 10:30. The advice I was giving there was to make sure the distributor is set to 10* and that it matches the 'reference angle' in the Holley Software. Sorry about that

Before installing?

[@alphagtr88]

Thanks for knowledge and different viewpoints from other install videos 👍🏽 definitely helped !

[@kylerobinson6102]

Mine showed up in the post today - Terminator X for a 1986 Mustang. Doing it in my garage.

[@paulcleckley5998]

Very informative video

[@mysticfox9469]

Great video holly should post your install videos on there site. I laughed my ass off when I saw that shirt. 🍻

[@white-kw3rq]

Good info!

[@elmaikonay552]

Just ordered the Holley terminator x, hopefully I can get it done well, since you provided us with a really great info, thanks

[@RegularGuyGarage]

Hope it helps you. Check out Donny B on KZbin too. He’s got great Terminator X foxbody stuff

[@johndoe-zb8bm]

What's up Dan,I appreciate the info. 💯

I’m so glad I came across this video I’ve been trying and trying to figure out if I was supposed to use both pink wires on my fuel pump relay spliced into the green 12 V trigger wire.. some cars have 4 wires some cars have 5 wires going into the relay.. It’s literally the last thing that I have to do for this installation so now I can finally finish!! Thank you 🙏🏼

[@TheModAddict]

I have 4 wires with only one pink. Do i splice into the one pink or do I use the pink and another wire?

[@TheModAddict]

Unless im not all there in the head, you say to hook the green wire to the TWO pink wires at the fuel pump relay under the driver seat. I only have ONE pink wire on my 90Lx

[@velr50gt]

I am currently using the microsquirt from the EFISource. Right now I have it very well tuned, and it has been a pain to tune due to fairly big cam on my N/A 347 stroker. I think the microsquirt is not as powerful (smart/quick) as the Holley Terminator so I am thinking on switching to the Holley. I also have the same problem you have with the injector connector tabs all broken up so that is also getting my attention. I feel I need better control of the fuel delivery. Thanks for sharing this video. Good luck with your project.

[@GearHead704]

Sever people want me to get the Holley system, but I'm going to stick with stock ECU for my cars I think, but it's cool you cover this. Also I would buy a shirt.

[@RegularGuyGarage]

I think for the SSP it might be a good system since you’re wanting to do a lot of racing with it. As for the convertible, the setup you have now is absolutely perfect for what you’re doing in my opinion

[@santasstang8798]

I love the shirt! I want some! Other colors though, and I laughed out loud as well!

[@RegularGuyGarage]

Yea we just used some left over material but could def do other colors for shirts and font

[@crazycali7]

Shirt is funny. Love it

[@arturo5819]

Matt at leech Motorsports is putting out some good videos on the holley

[@RegularGuyGarage]

Yea. I needed them about 3 months ago lol

[@samlaffosse438]

Kind thought running that green wire straight to power your fuel pump was a bad idea, I used it to turn on a relay with at least a 14 gauge power wire running straight from the battery to power my fuel pump. ESP if you have a larger fuel pump than factory (don't want your fuel pump to not have sufficient power ripping down the strip, go lean, and blow the motor). This was necessary for my 347 and would suggest for yours in the future.

[@johndoe-zb8bm]

Good tip! I thought he just wired it to the fuel pump relay? He snipped 2 pink wires and connected the green wire to them in a butt connector. I don't really understand it either, that's why I'm asking.. your saying don't do that? It looked like the simplest way to get it to work with what wires already exist.. thanks.

[@alexrollison-cote8124]

Between your video and the Fixbody install video Holley efi was super easy to install. Just takes a little time to wrap your head around everything

[@RegularGuyGarage]

Glad it helped!

[@kylerobinson6102]

I'm having a hard time getting the main harness out over by the brake booster area. Any tips?

Thanks man 👍 yea I’m trying to learn as much as possible so I can continue to tune everything myself from here on out

awesome t shirt.

How about some more info on your motor, heads..I am also using the 274hr on my 347. Any idea of what kind of power it makes? I've been watching and reading a lot about the terminator x, close to purchasing

[@79beans347]

😂🤣😂 that shirt is badass love it, I laughed my ass off when I saw it, that's genius man, gotta have it😂🤣 I don't have the terminator but it seems like you have explained it well for someone looking to set theirs up and I'm sure that this will help them get started

[@89gt5.0]

If im not mistaken it only uses 1 a/f sensor right?if so I don’t understand only monitoring one bank instead of both . You should always monitor both banks in my opinion . An intake leak could really lean one side out and you might never know the issue was there until it’s too late

[@bigmiami3763]

What did you wire you positive side of the coil too

[@kennyp4967]

I finally got mine today it only took 3 1/2 months too get

Just got the term x installed in my 95 it all lights up and works but when I try to start the car I get a no crank can’t figure out what I’m doing wrong

I know it’s late but how do I get a shirt?

[@victorsalomon3305]

Love your videos man thanks for your help all the time!! But man I'm trying to contact Holley, but is near imposible, so my question is when I try to load a tune to to the sd card it shows as a pdf file I know there are two load on to the desk top and one of them just tell you what you just load on to the desk top but the second one keeps loading as a pdf I use open it as and try internet explorer and now it goes to media player, what should it be open with? I might be my fault on setting a default on the pc or my kids playing on it, if you could pls give me a hint

[@RegularGuyGarage]

Ive honestly never had that issue. It should be a .terx file. Open the software and then click open global file and click on the file you’re trying to open

[@victorsalomon3305]

I does open on terminator x and saves normal, is just whenever I send it to the sd card or desktop it tryies to open with media player, and it does not say .terx file

[@alltorque415]

Which would you recommend more terminator x or to switch to carb setup?

[@RegularGuyGarage]

Knowing what I know now, Terminator X for the amount of options it has and what you can control with it. But nothing wrong with a carb setup

[@Scrapla1]

Some guy's have mentioned you need to buy a 3 wire GM style oil and fuel pressure sensors

[@RegularGuyGarage]

It comes with a oil pressure sensor and you can buy another pressure sensor from low-doller Motorsports

[@Wortheys_Garage]

Does your headlights turns signals etc still work?

[@RegularGuyGarage]

Yes. ECU only controls the engine.

[@ilike9s]

I'd like a shirt in gray.

[@datsdylan007]

Does it replace your engine bay harness?

[@RegularGuyGarage]

Yes, the entire engine harness gets replaced by this

[@parmsangha4091]

I did the install car cranks but doesn’t fire anyone come across this issue while installing it ?

[@troymason8738]

Are you getting rpm tach signal ?

[@Scrapla1]

I have a 347 NA with custom cam but I don't have the cam specs. Is there anyway to find out?

[@RegularGuyGarage]

You’d have to contact whoever manufactured the cam

[@Scrapla1]

@@RegularGuyGarage That's the problem I bought the engine years ago pre built from a old friend I have no contact with. It ran great had it tuned by a local Diablo Motorsports shop who used a chip on the stock ECU and they never asked specs they just tuned it. Theres no self learn feature or way to tune it without having the specs?

[@bonezshakergarage]

I installed the terminator x on my Mcarlen but I can’t get it started because the voltage drops to 10.1 when starting. Do you know what the fix is for voltage drop?

[@RegularGuyGarage]

I’d start off with the easy stuff, especially if you didn’t have the issue before installing it. Check all of your connections, especially the grounds and make sure they’re tight and have good clean connections. I added a 4 gauge ground wire from the drivers side of the block to the chassis to help out. After that I’d check to see if there’s any voltage drops at the starter solenoid. Could be a bad solenoid or even a bad starter. If all that stuff is solid maybe a bad battery.

[@bonezshakergarage]

Regular Guy Garage I had my battery checked yesterday and they said it was good. I only have one ground right now. I will add more

[@RegularGuyGarage]

I had to change the starter solenoid on mine right after I installed my terminator x. Check that out too. They’re known for going bad

[@jimmitchell3331]

Just tried to start my 306, brand new motor to the car. With the Holley, was unable to start it. If I make adjustments on my lap top do I have to hit save so it will download to the computer?

[@RegularGuyGarage]

If you’re using the usb link you have to “send to ecu”. However first start I would use the startup wizard on the handheld. Make sure you do the tps auto set at the end too

[@RegularGuyGarage]

If you’re making changes on the computer with the memory card then yes, make sure you save it and then upload the tune you made changes to

[@jimmitchell3331]

@@RegularGuyGarage any way I can get in touch? I’m a newb with this tuning just want to make sure I’m not screwing up my motor.
