So guys I'm in the middle of my det swap from a s14a blacktop automatic into a manual s15 spec s, I have everything needed engine, loom, Ecu etc no prop as got told could use the same prop, pulled the wiring loom and Ecu out today went to put the new Ecu in and found I've already ran into problems as the s14a wiring loom has more connectors at the Ecu then what was on the de wiring loom. Can anyone help me out? I gather the engine loom is the same with the gearbox battery etc? Any help would be greatly appreciated as I suck at wiring!! Mechanical stuff I'm all good with and can work out, but always have problems with the wiring. Plan is to try again tomorrow when I'm not tired and annoyed with it haha. Also sticking with the 5 speed gearbox from the de as I've heard they are stronger? Thanks Danny. If anyone does have any knowledge can you either comment or pm me on here and also text me on 07933049143 as I'll be at work tomorrow with no internet thanks again!!
