ShawnPreece Posted October 9, 2014 Share Posted October 9, 2014 (edited) Hi I'm currently fitting a HKS type 1 turbo timer in my supra, my supra started life as a manual non turbo but has had an engine swap and had a vvti twin turbo put into it. Iv put the HKS wiring harness in and am currently trying to connect the RPM signal wire and the Speed signal wire into the Ecu... The wiring diagram iv got doesn't seem to match up with the ECU (see pic) this is the 1st time iv done any wiring towards the ECU so just want to ask if it's just that it's a non turbo ECU and wiring is different although iv googled wiring diagram for non turbo ECU and still looks different or if I'm just being dumb and have missed something?

Not sure if I'm just being stupid or not Quote Link to comment Share on other sites More sharing options...
