Hey guys, I haven't found any wiring information on any of my usual sites and I have a client coming in an hour from now as a replacement booking for a no show. As I understand, this will be a bit interesting to find the wires I am looking for, if anyone can provide me with the colour and location of the following wires, I would greatly appreciate it.

Constant Power

Starter

Ignition

Brake

Tach

Any information as soon as possible would be greatly appreciated. Thanks.

Engine bay fusebox for starter and ignition, injector for tach, OR idatalink or fortin for CAN adaptor modules, far safer.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.

Quick question. With this particular vehicle, there seems to be a delay on the ignition wires, of around 10-15 seconds going on and off. The power does not arrive or leave the wire for a little while after turning the vehicle on or off. Does anyone know why this is? Or possibly another ignition wire that does not have a delay? Thanks.
