I used the Painless Hot Shot relay kit and it works fine:

Sure, you can do it yourself for less (switch + relay), but the kit is nice. All pre-wired, socket and bracket for relay and switch, includes circuit breaker and pretty much plugs right in. Totally solved my random no-start issue (and the starter contacts and wiring on mine is fine). Big advantage of the relay setup is you are now passing 0.1 amps through the ignition switch while starting, instead of ~20 amps for the starter solenoid.

No harm in doing so and just takes the load off the stock wiring and ignition switch. Plus the push button on the HS relay bracket is nice if you are working on the engine and need to bump it over with the starter. In my writeup, you describe how I added a male-female spade lug connector into the factory starter solenoid wire. Made them to fit the HS wires and that allows that relay to be plugged in w/o cutting any wires and if needed, it can be disconnected and the original wires plugged back together, say if the relay burns up out on the trail of something. Also, easy enough to carry a spare headlight relay if needed.
Now, my '85 has no factory starter relay, so adding one makes perfect sense. Later trucks ('86 and later I think) have starter relays, but the way they are wired, they pull the same ~20 amps of current through the ignition switch, so the relay really does nothing to take the load off of the switch. Probably wired this way for safety as you have both the ignition switch and starter relay in series, so even if the relay stuck on, you could still shut the starter off with the key. So a slightly safer system but less reliable having switch and relay wired separately.
Ultimately I want to run a second push button switch from the relay back to the dash for use on the trail. Save wear and tear on the ignition switch starting the truck in gear, just turn on the ignition and hit the start button and go.

Lol. A little slow on the uptake.
And yes, I would wheel it more. And going with these yahoos means body damage for me with no lift and 32's. I can't retire it to wheeler status quite yet.
