Help? CTS Plug Missing From Harness ECM 7730

Everything else seems to be there, does that 1227730 computer need it?
Anyone have a picture of where it is supposed to be?

Thanks,
Dave

Re: Help? CTS Plug Missing From Harness ECM 7730

The plug goes in different places depending on what type of EFI setup you have.

I think with TPI it's still in the manifold somewhere, but with TBI it's right out front in the center.

This is my mangled CTS plug, the socket on the bottom crumbled away from years of becoming brittle and the only thing left is two wires sticking up through it.


Plug right beside the waterneck here.

Thanks,

I was looking at my TPI Swappers Guide and they show the 2 plugs at the front of the manifold.
The MAF system shows a wire loom from the left side with the CTS plug and MAF sensor from the same part of the harness.
On my MAP the wire loom comes from the pass side with the plugs for the throttle body and 1 plug for the small sender on the front, but not the other square one. I should post a picture.
