Quick Question on the C191 (injector to ecu plug)

[702pjc]

I'm looking at removing the connector and just adding new bullet male/female connectors. I just need to know what size of gauge to buy. Any ideas?

The wire size is shown in http://wedophones.com/BMWManualsLead.htm next to the wire in question. I found 5 of the 7 wires going to C191 and they were either 1.5 mm^2 which is close to 16 AWG and .5 mm^2 which is close to 20 AWG.

the small pin size will work fine

Alright cool... Now, does anyone have the correct wiring info?

I know the harness has 7 wires due to the unused ground on the CTS but I'm curious as to which color is the one I don't need to use.
The coolant temp sender has two wired coming out of it. A yellow/brown and a brown/pink. The info on this link states that this combo is not possible...

The only wire I find missing on the engine side is the smaller gauge brown/yellow but the link says that it should be used?

Use brown/purple

Thanks nando.

Now that I've gotten it all crimped/soldered one of the smaller gauge wires decided to break out of the crimp... I bought the removal tool for the terminal but it won't work on this specific terminal... It's stuck!

So is there any possible way for me to splice this ground (orange/brown) into another ground wire or do the grounds need to go back to their respective pins on the DME?
