I need to extend my TPS wires. What size wire do I need and where do you recommend to get it from?

Measured with a set of calipers, the existing wires are 2mm external diameter.

I only need about 50cm x 3!

Cheers, Mark

Nothing special about them just use some suitable lengths from the parts of the Sierra loom going spare....

Just make the splices or connector are 100% ---- even a slightly iffy connection to a TPS can cause problems.
