Sonac Posted May 29, 2021 Report Share Posted May 29, 2021 Hi there, I want to convert my Celica ST205 from distributor to coil on plug. I have the coils and a harness ordered but I'm not entirely sure how to connect it to my plug and play ECU. I looked at the pinout for the expansion loom connectors are those don't seem to be suitable. Am I going to have to modify the stock harness to get them to work? Also I have the basemap running now but I can't get to a tuner for a while. I don't suppose anyone has a tune they could share with me which will allow me to drive around? The basemap is obviously unsuitable for road use. ThanksEDIT: Just re-read the description of the COP loom I bought from GT4 play and it seems they provide instruction for re-pinning the loom to make it work. And they also email a base map which allows the COP to function properly. Quote Link to comment Share on other sites More sharing options...
