PC3 Install for an 07

Hey Guys,

I'm installing a 2nd hand PC3 so it didn't come with the splicing block for the TPS plugin. I'm thinking I'm just going to solder it because I don't know where I'd get one of those blocks. Can anyone tell me what colour wire I'm looking for and in which harness it will be located? I found a wiring diagram online, and if it's right the wire is Grey/Violet, located in its own arm, going right to the TPS sensor. Hard to trust random stuff on Google for wiring though. Any help is appreciated, thanks.

I bought a 2nd hand one myself but luckily came with a splicing connector.
On the ECU under seat the smaller connect out of the 2. The wire your after is No.5. Lift up the ECU and twist it round facing it down and you'll see no.5 above the wire.

Hopefully this helped if you haven't sorted it yet.
