Question:
Could I get a wiring loom diagram for one of your harness?

Answer:
We have a few manufacturers for harnesses, which we have been dealing with them for many years. They were originally sent a harness that had been manufactured by another company for us that we are asked them to duplicate because the original company had closed. They designed the new harness, which is then their IP, we do not get involved in the design of the harness or have copies of this information. The only information we ask them for and get involved in is the interface connector and this information is provided on our website, where the wiring harnesses are listed. This information is also supplied with the harness on purchase.

The harness designs also evolve over time to keep up with technology changes. More recently they are modular and these are what we call our standard off the shelf or generic harnesses. Some customers also have them custom made by their own wiring company.

For all these reasons, there is no standard wiring information, the only thing that is standard is the ECU pin out information, which is available on our website and the interface information provided with the harness when purchased, which can then be used by an electrician to fault-find a harness if it has been damaged.

Question:

Are you able to confirm that I could use the spare wire (i.e. gear change light) to connect to a relay to allow the cooling fan to” run on” after the engine has been switched off?

Answer:

Yes, you can use the gear shift light output for rad fan control. You would simply use the switched negative as the negative side of a normal 30amp relay and use the output of the relay to power your fan. The instructions that show you how to wire a shift light using a relay are identical to that required for using your rad fan. You would simply then need to configure the output to come on at say, 750rpm and on at 85 degrees and off at 80 degrees.
