I have not seen a LS harness with a jumper plug in it like your first picture. Did you happen to connect the 2 or was it like that? If you can tell me what pins it goes to in the ECM i can tell you what its for.

I will check / route the wire back to ECM ....give information tomorrow.
Honestly i dont see any reason why there is a jumper plug...it is just connecting the same colour wires ....maybe it is designed to do a diagnostic at this plug ????


The second picture with the 3 pin round plug should be the oil pressure sender plug located in the center of the block behind the manifold.

I just checked some photos of the deinstallation of the engine.... so i found out that this plug goes to the A/C pressure valve..

The third picture with the heavy purple wire in the harness should have an eyelet on it not a plug. It looks like someone added the connector on your harness and removed the ring. The other side of the purple wire will go to the connector in the firewall which goes to the ignition switch. This wire should also be purple on the original body plug.

The plug on the 3rd pic is the other end, that means u r right.. at the starter side the purple wire is connected via a eyelet.
The end wich u see on the pic is plugged above the passenger wheel, where all the C100 / C101 / C105 plugs have been located.

That means this purple cable i have to install to the ignition switch ? or relay ?


Thanks again
