What year truck, what upgrades, etc.?
1986 Chevy short bed with a GM Performance Parts ZZ 502 with a new GM starter. New Ford starter solenoid wired from positive battery post to left post on solenoid. Right post on solenoid to original battery post on starter. Original trigger wire from starter is now on the Ford solenoid s terminal with the fusible links still in place. The mount of the Ford solenoid is grounded to the battery. Jumper wire from original battery post on starter to the original trigger wire on the starter.
Thanks,
Mike

Did the starter come with the crate motor? If so, it's probably the new gen starter with rare earth magnet design. I think it has to be wired differently. Marl Hamilton of MAD Eletrical had schematics for that conversion. I know I have the schematic, I'd just have to find it. I'll see what I can do, while maybe somebody else will beat me to it.

Yep, I thought I had seen this in the MAD literature.
'95 and later and crate motors use the new permanent magnet starters.
"The motor design becomes a current generator when coasting to stop (starter), and feed back causes the starter to stay engaged in the flywheel."
So you need the standard Bosch relay used for the headlight relay upgrade.
That's with terminals 30, 85, 86, 87 & 87a.
I'll describe it because last time I tried to scan, it didn't work.
F-Solenoid base has to be grounded which I think you've already done.
Batt + to left (big) terminal on F-Sol. Sol. right (big) to starter. "S" (small) Solenoid to original start wire and to relay 86. Relay 87 to starter small wire. Relay 87a not used. Relay 85 to ground. Relay 30 to F-Sol. right (big) starter post.
Come back with the results.

What is the benefit of running the bosch relay?
Why wouldn't I just run a wire from the "s" terminal on the ford solenoid to the "s" terminal on the starter and remove the jumper wire I put on the starter?

I believe it shuts down the starter once the motor fires. I'm not heavy into electrical unless I need to, and this one I'm not. I just happen to have the diagram from MAD Electric.
I'd suggest making a diagram, and follow the logic.
If you do try it your way, keep a fire extinguisher handy.
Good luck.

Hmm, hope it didn't burn down.
