We generally ship ECUs calibrated and ready to install. To do this we will require some information from your old ECU, Transmission and vehicle. Please provide the following when inquiring about a replacement ECU for a WTEC, 1/2000, CEC2 or 4th controls system.

VIN - 17 digit Vehicle Identification Number
Transmission S/N - 10 digit number found on transmission data tag
CIN - 11 digit alphanumeric found on original ECU
ECU+CAL - 8 digit alphanumeric found on ECU
We stock some complete wiring harnesses however due to the large number of variations it would be impossible to carry them all. We can order your replacement harness but lead time is generally a few weeks. In most cases wiring harnesses are repairable and we do stock many connectors and repair terminals to help repair your original wiring harness. If your harness is beyond repair we may have something that might substitute such as a longer harness or one with extra connectors. Please give us a call.
