does anyone know if a wiring harness is necessary to connect the hks type 0 turbo timer? if so, which one... the universal? any other parts needed for the install? thanks.

I didn't use a wiring harness. You just need to know what wires to tap. If you need more info I'll find trace back how I wired it.

thanks! if it's not too much trouble.. that would be great. any other install tips would be much appreciated as well. :)

*bump*... any help would be appreciated. also, does anyone know where to plug in the rpm signal wire on the B15 ecu?
