Hi Guys
Am in need of some help regarding wiring to and from the starter relay because i cant get the starter to crank,
Am in the process of doing a engine conversion and running a standalone ecu.
I've searched for various diagrams but some of them are poor quality once you zoom in.

I no the thick black wire is a live and the thick red/blue goes to the starter but am unsure where the smaller gauge wires goes to. Any help/detailed diagrams would be great

thanks
andy

Hope this helps you out! Not sure your year or model but these are for a 2005 C2S. Should be enough to guide you…

Does your dash energize normally?

that's awesome, thanks' a lot. its a 2006 c4s so i presume i would use the earlier model?
just out of curiosity, what program/website are you using for the wiring diagrams? it could be useful for me later in the build.

yes, as am using a standalone ecu with a different engine there's lots of wires/sensors that are not needed, I've got a feeling its some relay I've missed but until i can chace back the wiring am not sure

There is a cluster of relays just above the fuse panel and one has to do with the starting circuit.

That's Relay Support 1




...and there's also relay support 2 back by the DME under the shelf

username vtecknowledge and engine conversion with a stand alone. Let me guess, K24 swap?

I have access to Mitchell1 Prodemand at the shop I work at.

Based on the picture that you showed I think you are the later production.

you would be correct ;-)

I’m waiting for someone to drop a kit for the K swap and see how many people go for it. It’s a robust platform with a lot of potential.
