Repairing fusible link multi-connector?

After more poking around under the hood today I discovered that, at some point in the past, 3 fusible links had blown. They are the ones coming off the 5-way multi-connector just below the starter relay.

A shade-tree mechanic did a butcher job and replaced one of the links, bypassing the connector (sort of the way The Book recommends). The other links were repaired by twisting them together then running plain wire *directly* to the POS battery terminal (NO Fusible Link! ).

After looking at all the black tape and loose connections, it's a miracle the truck is running as well as it is. So, the next project is to replace the multi-connector and all the fusible links.

Can this section of wiring harness/connector still be purchased from Chrysler? That would be my first choice. I guess I could look for a pristine one in a junk yard.

What do you all think about removing the existing connector and replacing it with a terminal block (similar to this one)

Anyone been down this road?

Thanks!

Can you discern a part number stamped into the plastic of the old connector? If so, you might be able to hunt down a relic collecting dust on some dealer's shelf. I've found a number of things that way. Trick is to find the right dealer, because I had to call around my area until I found a dealer with a "can-do" attitude who could get on the national computer system and track down the part (if you have trouble in your area, Google Newcastle Chrysler in Maine, there's guy named Fred there who will find what you need if it exists anywhere).

I wouldn't hesitate to wire up something new yourself, though. A lot of times you can do even better than the factory. My wiring at the relay is different than yours, but I've replaced all of it and it's not hard to do. You have a good soldering iron, pair of crimpers, and heat shrink tubing? A good source of quality wire is Waytek, by the way.

I think that terminal block would work fine.

I'll take a close look at it. If I can't find a part number, maybe I'll hike over to a few dealerships with my service manual and see if they can come up with something. Would the service manual have a part number for a chunk of wiring harness?

Thanks for the lead in Maine.

Yes. I'm not at all squeamish about cutting, soldering, shrinking. I'll have to do some reading to make sure I get it right, but I think that may be the easiest way to go. Mounting the connections on a terminal block seems to be an elegant solution.

Thanks for the feedback!

Yeah, I wouldn't hesitate to go that route either... Personally I'd rather go that route, because as Meg says, any wiring that you make yourself (As in soldering and shrinktubing) you know is going to be better than factory... They were worried about time and cost, where as we aren't

Good points. I planned on checking the junkyard for a replacement harness but I might end up with more problems than I have now. I'll start shopping for wire, fusible links and a terminal block.

Can anyone suggest a terminal block that would work well for this application? The one in the link I posted earlier would work, but I'm concerned about the exposed terminal:



I don't like having that thing uncovered under my hood (corrosion, grounding risk, or worse).

Could I cover the hot terminal with some PlastiDip tool dip perhaps??

A block of some sort with a gasket and cover would be slick.
