Brand New 7MGTE Wiring Harnesses - $999

[Dr Tweak]

Hey everyone, over the past several years we've gotten many requests for building brand new 7MGTE wiring harnesses since Toyota discontinued them. I'm happy to announce that we can build new 7MGTE harnesses for the '91 and '92 model engines with the newer style injectors, 02 sensors, knock sensors, grey 26/16/22 configuration ECU plugs etc. If you want to retrofit an older model 7MGTE with the newer style parts then this harness will work just fine. No core harness needed for model years '91 and '92, if you are using this in an older vehicle then you will need to either supply a core harness or pay the $300 core charge. (The core harness is ONLY used for the body connectors that plug into the fusebox and dash harness, everything on the engine is brand new). Turnaround time on these is normally 2-3 days. The harnesses are priced at $999.

So what price range are we talking? I need to start saving.

agreed, what price range Doc?
and what about 88 harnesses?

[Dr Tweak]

Whoops, forgot about that eh? They are currently priced at $999. If they get really popular I might be able to lower the price but as of right now that's where it's at.

As for the older model Supras, it's like I said, you need to supply a core harness for us to get the body plugs off of and then you'll need to swap to all of the newer style electronics. We COULD reuse your ECU plugs so you can use the original 7MGTE ECU with the 10/18/24 pin configuration, and we DO have the older style injector connectors, however you'd have to swap the 02 sensor and knock sensors for sure.

Just to be sure for my 89+ grey plug I would have to send you the complete engine harness and then just switch the 02 and knock sensors over to the 91-92 style.

Also if I send you EV6 style injector pigtails with the harness would you be willing to switch those for me?

Awesome! Well priced and well timed. There have been TONS of threads about new harnesses or harness repairs lately. Having recently redone a harness and knowing the work that goes into not only allocating all the parts, but also assembling, I can fully appreciate this offering. Had you posted this 9 months ago I may have been your first customer!

Post some pics of a finished product and good luck!

Yeap, not a problem, we have them here as well so we can do that for no extra charge.

And correct, you would need to send us the '89 harness and then swap the 02 sensor and the knock sensors. Bear in mind that we can supply a male mate for the new style 02 sensor plug so if you want, you can send us your OLD 3-wire 02 sensor and we will put the matching male mate on there for you, that will save you from having to buy a new 02 sensor. The knock sensors, however, you have to change.

Given the amount of work that goes into making even a simple harness, this is a really good deal.
