Hi everyone! I know I haven't been around much and I hope you've all be doing great. We've been super busy here at Tweak'd Performance and one thing that I've FINALLY taken some time to set up is building brand NEW 3SGTE, 4AGE and 4AGZE harnesses for the Celica (or anything else for that matter). Of course you know we've been doing plug and play wiring conversions nearly 10 years now, but there are times when nothing but a brand new harness will do.

We can build these for the 20v Silvertop (auto or manual ECU), 20v Blacktop, 4AGZE AE92, 4AGZE AE101, and 2nd/3rd/4th (ST215) 3SGTE engines into any chassis. The engine harness itself is completely brand new, that means new connectors, terminals, wire, etc. The only thing we need for your original Celica harness are the body plugs that connect to the body harness/fusebox.

Our standard looming method is a huge upgrade over factory, braided sleeving on all branches and split braided sleeving for the main section of loom. These harnesses are tucked, look great, and are also available with a MILSPEC firewall connector for anyone looking to go for that really high-end look.

Besides building these harnesses for any revision of the OEM Toyota ECU, we can also build it straight to ANY standalone EMS that you want to use, for no extra charge. In fact we keep the ECU connectors IN STOCK here for the AEM 30-6050, Haltech, Motec, Vipec, and ProEFI ECUs. Turnaround time for custom harnesses is about one week, we strive to keep OEM-style harnesses in stock and ready to ship. Here are a few pics for your enjoyment. New harnesses start at $650 - $800 depending on the version.

You can run any injectors, sensors, etc. We have GM 3-bar map sensors, AEM map, AEM/GM IAT, Bosch injectors, ID2000, ID1000, GM LQ9 coilpacks, etc etc etc all in stock. Generally there is no extra charge for changing what ECU/EMS you're running or injectors, if you need a LOT of custom work done like adding and moving things around, it may cost an extra $100 - $200. You can also run a flex fuel sensor (we have the GM/Continental connector in stock), fuel pressure, wideband 02 (we carry the LSU4.9 connectors in stock), boost solenoid, etc. Anything you want deleted or moved just let us know.

Your best bet is to message him on his website. He doesn't come here much anymore.
