I never raced I just like the cruising and look and sound of course no stereo can’t hear the music anyway with that set up but now took it all off and installed all air ride with 24’s and took blower off but thinking about putting it back on because even thou the crate 572 is got 720 horse power I can really tell the difference with it on, it’s like having 2 engines I mean man it is serious horse power.

Is there a certain place that was used for the information on the wiring? My pickup is 1990 and is the work truck model so shes super basic. But id like to know of theres a website or anything that the information was used from. My pickup was originally a 4.3 v6 pickup with a 5 speed now i have a tbi 5.7 v8 in it now. But i also have a ls 4.8 from an 06 silverado i want to get stabbed in my pickup this summer. Thanks in advance!

[@chillletmeslide3840]

So how does the harness get power from

From that bus bar where all the wires was on

[@aaronwalpole8019]

Is this pretty much the same concept as a 95 harness? I know there is a lot more to a 95 but its one of the steps stopping me.

[@TevionsGarage]

It’s pretty close

[@aaronwalpole8019]

@@TevionsGarage Not gonna lie, this is the hardest part for me. this harness was in bad shape when I saved the truck from the crusher. The Harness is cut in half so Trying to pick up the pieces and make it whole again. Seems that nobody has a vid on a 95 harness. Yours helped me thin out most of the BS but with a bulkhead on driver and passenger side, hard to make calls on what is needed on both sides.

[@TevionsGarage]

@@aaronwalpole8019 are you swapping it ?

[@aaronwalpole8019]

@@TevionsGarage Yes sir, I swapped it already, have already fired it up. but this harness is horrible. Id show you the pictures if it would allow me to post or message you on here.

[@ajf1006]

How do you unplug the main harness from the fuse box on the driver's side?

[@TevionsGarage]

It’s a bolt in the middle after you get that all the way unscrewed you have to kinda pull it out like in a finesse kind of way . It’s going to be rough but I tried to get the 2 top ones off first one by one and then bottom it’s a lot of grease in there so it’ll be hard

thank you for tuning in beloved 🦅

[@JoseCruz-qf6ui]

How does it work without the ecu? Do I need to do this if I’m going to use the terminator x max?

[@TevionsGarage]

Because when swapping the car the ecu doesn’t power anything that’s for the old motor . only things you need comes out the bulk head on the driver side . you need to do it for pretty much any swap

[@JoseCruz-qf6ui]

@@TevionsGarage Ohh, I always thought the computer controled controlled them. Are you in Atlanta? Is that other small red 12v wire also switched power? I need two 12v switch power for the terminator x max. So the starter wire will still allow me to turn it on with the key. Rn my wiring is a mess, I’ll try to trim the original and start all over.

[@TevionsGarage]

@@JoseCruz-qf6ui watch my Monte Carlo video I explained it well on wiring it up it’s the exact same , and Naa Kansas City MO , and yeah you could get a distribution block and run one wire from the fuse ign port under the dash to it and the other 2 from the harness to it and that’ll work. making that whole block a 12v key on
