Wiring Harness Conversion Service - Gen4 / Gen5 3SGTE – TCS

The most important part of any engine swap into your Toyota MR2 is wiring. We spend countless hours fixing wiring harness work on these swaps when customers decide they want to perform the wiring conversion themselves. Save yourself a TON of time and headache, and just send it to the professionals.    Please Note: The additional cost for the Gen5 3SGTE swaps is to remove the factory immobilizer that is built into the Gen5 ECU. Without this service, your car will NOT start.    Upon ordering, you will need to send us the following:   1. Your original engine harness (the one that is currently running your car) 2. Your Gen4 or Gen5 engine harness 3. Your Gen5 ECU (if you selected Gen5 3SGTE swap)   In roughly 2 weeks you will receive back a fully plug and play engine
