1985 C4 HEI module harness
I need to replace the wiring harness that attaches to both ends of the ignition module inside the distributor cap. I have searched and searched but cannot seem to find one from a parts supplier. The main problem is I do not know the GM part numbers or the right name to call it. Can someone tell me who sells these and what they are called or what their GM reference number is? Thanks.

I believe the part number for one of the two harness is 1892261 which was superceded by part number 1892260. This is the harness that connects to the ignition coil at the cap and has 3 wires. The other harness is the 1986260. It has a connector at the other end that plugs into the main engine harness which goes to the ESC control module, it has 4 wires. Both of them are referred to as a terminal blocks. You may want to confirm that I don't have the two part numbers reversed. I'm pretty sure the one that goes to the coil is going to be the cheaper one of the two.

The side that connects to the dist cap w/2 wires on module,
from Autozone is called or found as "Capacitor" part number "U518" about $10
from Napa its called "capacitor and terminal block" part number su231sb or su231 costs $12 to $21 thats using my area code for pricing.
From Ecklers its 32973 $ 21.95
As for the other side of module with 5 tabs 3 of those goto the 4 wire harness that plugs into main harness the last grounds under module (they like to break the plastic tab that the cap sits on top of. I havn't been able to find this part from AZ or napa, But ecklers lists it for 79.99 as part number 37816
I would think this can be found at a dealership or GM parts

Wingralf, those are some good Eckler's numbers for those parts. With them you can see the actual pic of the parts. The one that goes to the engine harness is one expensive harness. GM parts direct and Rock Auto have part using the GM number I previously listed, expensive too. This is a hard to find part trying to search on the internet because of it's description.
