D Jet issues continue, Wire routing questions Options

[robkammer]

All: The intermittent fuel pump issue still lingers on our BB. Can anyone tell me where the wire (or wires) that feed pins 12 and 14 on the 14 pin connector are routed from the battery? It's obvious that it goes into, and returns from the hole in the firewall. But does it go all the way to the dash, or just under the passenger seat?

And the color, is it red/white or red/yellow?

This seems to be the cause of the problem. And check out my OBD 914 version below. Only way I could figure how to determine what was failing.

Thanks James, great drawings. I'll be back at it again today. When I left it Friday it was running and idling just fine. Went out yesterday expecting it to start right up, but no power to the fuel pump again.
I didn't have a lot of time yesterday but I did check power at pin 14 and 12, all good there. I'll run the 22 step test AGAIN today, and double check the contacts you point out.
I've attached a shot of the wiring harness from the battery to show that it hoes through the firewall to an as yes determined point of return. That may be moot as the #14 pin seems to be fine.
Pulled out the Stoddard relays and put the old working relays back in. Hew relays are disappointing. No pin numbers in the casting, and no diode in either the black or red version.
Update later today!
