How to Select the correct harnesses for your Holley Efi Install

[@FlatLineRacing4650]

Glad you made this video!!! In the beginning I was a little lost but I figured it out. Now friends and others ask me to do their harness. I have no problem helping, but now I can direct them to this video of yours. Thanks again for doing this.

Very concise and informative. Thank you for taking the time to show us

Great video, I really appreciate the information as I'm considering a dominator to control my setup with dbw and 4l80, over a terminator x with the can i/o module mostly for ntk and second oxygen sensor support After hearing Matt Happel's reasoning on the sloppy radio show the other night with you guys.Also it seems like it will future proof me from running out of inputs and outputs down the road.

Awesome video Devin, as others have said very complete and concise description and explanation. Thank you for every video you create.

[@whyamihereg]

A plethora of information job well done!!

[@talleddie81]

Thank you for the great content. I recently found your channel when Kevin from KSR mentioned you in one of the sick week videos. I have a turbo mustang that I would like to re-wire next winter, this information is really helpful.

[@sorscode]

Great video sir, as always.

[@robinwendt5527]

That was really awesome and most applies to what I'm building but I wanna order your main harness with it @ least I think that's what you were building about 6 months ago I dunno it wasn't completely manufactured and available yet.. you had a prototype @ the time of the video

[@theholleyefiguy]

Yes it's on our website hcrinnovations.com

keep them coming!

Devin. I would love a video on propperly ground a shield wire. Is it ok to ground all your shields to one point or maybe only at the sensor end of you wiring per sensor? You have great results and logs so Im sure your doing it correct.

I’m out of Inputs on my terminator x in my mustang and swapping a dominator in . I’m wanting to add 2 step off the clutch switch and flex fuel sensor what input harness would work best

[@fisherfn.6161]

What do i need if i already have a main engine harness i just need harness to wire stuff like transbrake dome pressure and stuff like that

[@Aancion01]

Dear, I would like to install a Terminator X on my Mercruiser 350 Mag MPI 1998 to replace the burned MEFI 3. Can I ask you what is the best kit to buy to get the most Pnp harness as possible?. Thank you in advance

[@vandettabuilds6641]

I watched a video where you said don’t buy anything from summit or places that don’t care about the customer Buy from someone that backs the Holly product I bought from you I answered all your questions about what car and engine I had but I was sold the wrong shit completely wrong shit I hope you guys have it figured out now for the next guy buy the time I had to buy all the extra parts to run the terminator x max I was over 2 grand including the terminator I got from you OUCH

[@theholleyefiguy]

What was wrong ? I don't recall any of this

[@vandettabuilds6641]

@@theholleyefiguy I ordered well I thought I wanted a Holly HP so I ordered it from you girl friend. Like I said before hand I told her everything about my engine I received the HP but I does not work with drive by wire. So I sent it back and got the term x max I have a 2007 LQ 4 DBW i received a term x max but my injectors wouldn’t fit the harness I had to buy fuel injectors that cost 500 bucks to fit the harness she wanted to send me adapter harness wires there was no way I was going to plug little pig tail extension wires on to my fuel injectors I had to buy a new throttle body to fit my drive by wire but I didn’t care about the throttle body I got the feeling that my order didn’t mean shit to anyone I’m a hard core budget builder I am very careful where my money goes to build my shitty little vehicles out here in utah

[@fisherfn.6161]

What do i need for just an engine harness and 1 input and output harness i dont have that many accessories

[@bdevastation3609]

hate that using trans control on the Terminator X max doesn't unlock the inputs and outputs in J4. MAYBE that will unlock in V3???

[@cotyliberty2819]

So the software in x max doesn’t allow access to the inputs and outputs of j4?

[@jplperformance9073]

So I need a dominator

[@jplperformance9073]

I have a Terminator X. Can I run two wide bands. One in each header collector?? I wld think it would tune better. Thank you very much for the video

[@theholleyefiguy]

Dual o2 sensors is dominator

[@joshholley5732]

I noticed your website has a (Virtual Holley EFI Consultation Service). Can I buy a couple of hours and you help me set up my pin map? I’m getting ready to finish the wiring in my car and it would help me sleep at night knowing once it’s done, it will work properly lol.

[@theholleyefiguy]

Yes sir we do that
