New Member - '86 Short Box LS Swap - TerminatorX

[Ponchopilot86]

Hello Y'all!
I am an old school ex Bodyshop guy doing a LS Gen3 5.3 & 4L60E swap on my C10. Going to install a Terminator X MAX and WIRING is not my thing. The Terminator plug in looks easy on the LS, but how about the wiring into the existing Harness/Connection block? any help or past posts you know would be appreciated! Thanks Y'all.

I did a Gen3 5.3 in mine. Used a PSI Performance harness and PCM. Those guys are good and will provide tech support. Their installation manual was good too. There were only a few tie ins from the PSI engine harness to the trucks harness which are shown in the installation instructions. I left some of the original truck harness (in the engine bay) installed since it had a couple wires on there for sensors and power at the starter etc.

Do yourself a favor and sell that Holley junk. Go order a BP or PSI harness and use a GM computer. Much more reliable, everybody I know with the Terminator has nothing but problems.

Agreed with Elliot^ I used a PSI harness, those guys are great for customer service. There's 5-6 wires you have to tie in together to get it running. I've got a 5.3/4L65 in mine with 30k miles on it now, it's been flawless. Also, go join the LS Swapped Squarebody GM Truck page on Facebook, TONS of good info there. There's a "Files" section with all kinds of info/wiring diagrams/etc. Scotty Baccus that runs the page also makes swap mounts/fan shrouds/etc through his company Tejas Steelworks. Highly recommended.

Get a PSI harness and its plug and play. Lots of tuners wont touch terminators unless they do the install.
Trust me. This is my thing. Unless your doing some kind of forced induction then terminator is worth it.
Plus terminators are NOT SELF TUNED as they say. PERIOD. You caN LOOK THat up. You will need a tuner
no matter what.
