Wire Loom for Throttle Cable
Anyone know a part number or place to find a wire loom for a 1991 5.0 TPI car? It is the one that holds the throttle cables above the intake runners (top drivers side)? It is a 3 position loom that mounts on a post that goes into the intake maifold. The top half broke when I was replacing the fuel injectors and I have not been able to find a replacement. Unfortunately, there are no bone yards with parts cars within 100 miles of me. Thanks.

That is actually a "spark plug wire" retainer . The OE number is/was 8917256

Re: Wire Loom for Throttle Cable
Thanks for the suggestion but the one you show in the picture is a 4 position spark plug wire loom. It separates plug wires but has no way to anchor to the manifold post. I am looking for a 3 position loom that is used on the throttle cables to keep them routed off of the top of the engine. Appreciate your help but I need to keep looking.

Re: Wire Loom for Throttle Cable
Very interesting. Thank you. Now I see where you got the 8917256 part number from - its on this exploded view diag but it is not the one mounted on my block. Here are 2 pics of mine. As you can see, it is a 3 position loom mounted on a shaft that is screwed into the side of the air intake body.
The bolted side on mine is fine, the top clip is the part that is broken. I will keep looking but I really appreciate your help with this. It is a very minor part, but I want to find the exact replacement.
