BINGO!!!

Add to that it gets the job done and it’s money well spent. The Stancor is not attractive and none of these parts last forever. This is not a critical part. In the event it fails, you can still start the truck with a screwdriver on the GP relay.

Remember, I’m not cheap - I’m broke!!!

Its a HUGE amp load. You will need to extend the wires in a way that does not increase resistance or short out and burn the truck down. The 12v supply to relay is HOT all the time and tees into the harness wire that goes from batteries to alternator.

I rarely (never?) see DIY wiring that meets my standards, so I could never recommend anyone do this unnecessary mod.

not enough gain for the work involved, just wrote it on the list and scratched it out!

I recently installed the Trombetta GPR based on the recommendation from Chris and it was a perfect fit. At about $20 and the trusted advice from friends like Chris and Jason, it was a good choice.

I was interested in replacing the starter relay as well, so I delved into the Trombetta literature and found a good replacement with 3 posts with the consultation/validation from Leonard.

Trombetta starter relay link

Leonard recently installed the starter relay and said the mounting tabs are inverse of the OEM, but it is a fit. I have thoughts of installing a nutsert in the fender or perhaps another mounting method if the inverse tabs are not to my liking.

The Trombetta GPR is a good replacement and a fraction of the cost of the Stancor/White Rogers which does not fit well at all in my opinion.

Below is a picture of the Trombetta GPR in the OEM location on my truck.

I have one of these in my box-o-truck-parts for if/when that Stancor ever dies. Bought it for my Mom's E99 but they ended up taking it to their overpriced shop and they put an OEM replacement in I believe. (Probably just charged them for the OEM part and put a parts store brand in lol).

Did you ever wire up that glow plug momentary switch?

Brandonpdx, I'm not sure if that question was directed toward me or not, so I will answer it based on my experience and if it wasn't the intended recipient may answer later.

Yes, and I like the functionality and GP safety it brings to the table.

I thought it was fun. I performed this mod with the Stancor relay on the last truck - moved it to the fender next to the starter relay. Had manual hubs on that truck so removed the 4wd pulse vacuum hub-lock solenoid to make room. There's a writeup in the Tech Folder that shows how I did it.

Yeah, it's possible the way I did the wire extension is iffy. If I did it again, I would bump up the GP wires one gauge to account for the extra length/voltage drop. I did enlarge the 12V supply wire gauge, and took advantage of the fusible links in that supply circuit for safety. Seemed to work well for the few months I had it before selling. I miss that truck.

For the current rig, I went the Trombetta route described in this thread. I would still like to open up the valley for better access at some point, especially with those large diameter HPOP lines in there now.

If it helps anyone on the fence. I use Trombetta relays on my Western plow. I have had the same one for at least 6 years, no issues what-so-ever. In fact, I have never had one fail....I hope I didn't just jinx myself...

the trombetta is used in alot of commercial applications. I became aware of it researching the dieseltop.com. They come on alot of snow plow rigs and a readily available all over the country.

I've never gone looking for mine, but I know it's not on the fender where my Stancor GPR has been mounted for nearly 7 years now. https://www.ford-trucks.com/g/album/2843812.
