Want to add some circuits in the rear fuse box of 2019 nox. The cavities in the plastic are empty so I just need to know where to buy crimps to put on wires and snap them into the fuse box. The one side of the fuse slots already are supplied with 12V. Also same for the 2 empty slots for relays in the rear box. Want to snap in some wire terminals for the relays.
I have searched and find various vintages of fuse terminals, not knowing if they need to be GM specific.
Anyone know where to get the fuse/relay terminals? Going to check with dealer, but figure all they will come up with is seeing me a new body harness.
Been searching everywhere for the crimps. Nothing seems exactly what is currently in the fuse box.
Want to add several circuits for tow package and mounting curt bluetooth brake controller in the rear fuse box area. Think I will be doing 3 or 4 relays and 3 fuses. Need to isolate the brake controller so I can power cycle it to force recalibrate(leveling).
Getting the terminals/crimps will make the install much cleaner. Hate to go to a u-pull-it junk yard.
Try a search for "Delphi" terminals and connectors. There have been many configurations of the fuse box terminals through the years and at one time I knew that Delphi was either a division of GM or their supplier.
I found the terminals at the dealer. At the parts department, they have trays of crimps but they have no cross reference to what the crimps are used for. The parts person said when a tech needs a replacement crimp they take the crimp from the car and manually search through many trays of crimps to find one that matches. Anyway, they let me go into the stock room and search thru all the trays. I found the micro relay terminals and the mini fuse terminals....
The fuse clip part number was 4-965999-1 in a tray labeled SPX Kent-Moore Lear J-38125-Tray 25. The label said call 800-GM-Tools to reorder.
The micro relay terminal was part number 15344769 in a tray 23 or 24 labeled Delphi rather than Lear.
It is a shame that GM service tech's don't have a resource to tell them the proper part number crimp to use, left to guessing. There were many crimps that were close but not exact, some just 10 thousandths of an inch difference. Not using the proper crimp may lead to intermittent service issues in the future and can be very expensive time wise to track down. I'm not 100% sure of my selection.
Did look at mouser and digikey. Mouser lists the crimps but no stock and generally has 3000 piece reel minimum for these particular items. Normally they would be my go to place for the parts and rather disappointed the parts were not more available. The trays at the dealer appears to cost about $330 each on some sites. I ended up with $2 per crimp at the dealer for something that might cost 10 or 20 cents if mouser had it as stock.
