The Helms for my '87 confirms this. The 4+3 transmission definitely has this relay. I would trust AGENT 86 and the Helms long before Mid America

I noticed Ecklers had this "overdrive relay" listed as a new item.
Exact same part.To diagnose either relay swap the plugs between relays.

If you're gonna order online, go here:

One on the top, $10. Cheaper than midamerica I bet. Or you could just drive to the parts store and ask for a fuel pump relay.

The GM Parts & Illustration Dealer Guide says that the 85 & 86 FP relay and the OD relay are both GM part #14078915. You should be able to get it online or at any auto parts store using the GM #.
