With a radio hobby you're probably better equipped and less nervous than I'd assumed -- I'm just no darn good at assumption. So let's just forget all of the last instructions and either round up four clip-lead jumpers or fabricate four, with clips or uninsulated male terminals on one end and insulated females on the other.
What we want to do is to remove the relay from the socket, and hang those four jumpers between the relay and the socket on pins 30 (common), 85 (coil -), 86 (coil +) , and 87 (normally open). Then start the truck, and:
Gold is 5%, Silver is 10%, none (no tolerance band present) is 20%. "Get Some Now" used to be the customary mnemonic device back when we worried almost not at all about giving offense.
If you'd rather do that than use jumpers, yeah. Hang the resistor in the socket from pin 85 to 85 to simulate the relay coil being there.
I apologize for presenting a half-dozen different ways to accomplish the same objective -- it's an old habit from a long career of MacGyvering.

- Measure and record DCV between pins 85 and 86;
- Measure and record DCV from ground to pin 87;

- Smile because no one had to crawl under the truck after all.

If you like the risk of unpleasant surprises, you sure can. Stab that folded end a little too deeply and it'll hang up on the way out, which tempts most guys to just yank on the little fasty nucker with pliers. Which tempts that female terminal to deform or break, and is even more tempting to one that's spent the last decade and a half rattling around under the hood of a pickup truck suffering the indignities of corrosion and mechanical shock and vibration.
In my little book of dammits, the careless repair is the one that gets you from your nice, warm, well lit garage where the damage is done to the middle of nowhere in the middle of the night in the middle of a blizzard where it becomes a total failure that might escalate into a self-imposed death sentence. That's just not a thing a guy who loves life does to himself.

Bunker: I hope your grandbaby is well and home by now.
UnregisteredUser: I was thinking more like, let's say, a staple, or an opened up paper clip. I'm just dying to see the results! I know we will fix this, but the suspense is killing me.

The leads flopping around are what usually catalyze the idea of folding them over into a U or collapsed U shape so they'll stay stuck, and that's when they'll hang up on removal.
It's probably a failed solder joint on a component inside the PCM, or a popped driver -- but that part only matters if someone's going crack the thing open and dig out the potting material which is a massive PITA. I've never been able to get my hands on the JTEC schematic so a component-level repair would require a bit of hunting to identify which component drives the wire, but once identified it'd be straightforward... if a guy is set up for and good at SMD soldering.

message from Bunker
Bunker's grandson had to be hospitalized, and he asked me to post this for him from 2 days ago:

Going to be a crazy week.
thanks
Tom

hello all just a update whats going on here, my grandson is still in Hospital and the surgery went ok. that hand to spate the two veins and put stints in them to keep them from collapsing. the little guy has a long road ahead. he has a legion on his liver they have to get off and the worst part is they have to literally break his skull and reform it because of some rare thing. then he has to stay in a helmet kind of deal for along time until it all heals up. all this before his 1st birthday. but each time they have to wait until he is stronger before operating. thanks to all who have ask and concerned keep the little guy in your prayer's and thoughts. I`ll be back online when I can spending allot of time in Savannah, GA where is is. Again thanks to all of you for your help and concern.
Hope everything turns out well for him.
