Help with identifying wire... Pictures inside. Thanks in advance.

Can anyone verify that the cut wire is indeed a ground wire? I think that is what it looks like per the TSRM diagram, but wanted to make sure my eyes weren't playing tricks on me. Also is there a location for which it should be grounded to, engine or chassis?

Thanks in advance guys! Much appreciated.

Where is it coming from?

Could possibly be a ground. Could do a voltage check.

That looks strange. The insulation looks a little too loose to be the factory Toyota wiring. There's a ground wire in that area that should mount to the intake manifold/plenum.

Do you have anything grounded to the intake manifold on the underside? It'll be hard to see.

I'd do a resistance check between that wire and ground or that wire and the E1 port of the check connector. It should be connected to those if it is the intake ground.

Also, buy a new TPS connector. http://www.tweakdperformance.com/onlinestore/index.php?main_page=index&cPath=2

Unfortunately, that's not an option any longer.

Effective Jan 2012, the OEM has DISCONTINUED certain connector housings for the 7MGTE wiring harness. Therefore, we will use good condition, used connectors sourced from core harnesses. The connectors that we have to reuse are: knock sensor plugs, injector resistor pack plug, MAF plug, TPS plug, and noise filter plug. No other option exists at this time.

Nooooooooo. I thought he had found a new vendor for them. I remember something where he discovered another connector would clip on.

It's wired into the harness appears about the level of the injectors. I'll do the resistance check, thanks for the tip.

And I'd love to find a new TPS connector among some other connectors.

Thanks for the tips guys.
