New 4A-GE 20V Blacktop engine harnesses!

[TweakTech]

This is a brand new engine wiring harness for a 4AGE 20v Blacktop swap into a Corolla AE86 SR5. These wiring harnesses are built using new wire, new OEM terminals, and new OEM connector housings. NO CORE HARNESS REQUIRED.

For GTS cars - these harnesses CAN be used, but we need to wire in the windshield wiper plugs for your original harness. We can do this for you at no additional cost, but you will need to send your GTS harness to us.

The harness includes an EFI relay and a fuel pump relay (SR5 only) with a lead. It is guaranteed 100% plug and play.

Several looming options are available including braided sleeving and extreme-duty heatshrink looming as well as MIL-SPEC upgrades for the ultimate in harness protection and a clean show-car look:

Prices start at $449 +shipping
Add COPs - $50
Special looming (braided or heatshrink) - $180
Mil-Spec connector - $300

Standard Looming:



Braided Sleeving:



Extreme Duty Heat Shrink Loom:



Mil-Spec firewall connector:

Whats the wait time? This looks legit as hell!!

[TweakTech]

We do have SOME in stock, but depending on your particular setup, there might be a 1-2 day build time.

Ok, I'd be looking for the basic harness for now. Do these come w/ the TE1 & E1 diagnostic terminals?

[TweakTech]

Yep, we have a 2 pin connector wired in for diagnostic purposes. I currently have one set up for COPs, and one set up for distributor relocation. Both are built for an SR5, but can easily be converted into GT-S spec.

I would like to order a basic version with COP add on. I do need it converted to gts spec, but can u guys add the wiper connector without me having to send in my harness?

Here too.

[TweakTech]

We need your GT-S core harness for those connectors.

I believe this thread belongs in the Classifieds section.

I'd love to know where to buy OEM harness connectors... I have to build my own harness...
