Morning.
This may be the last one for a while, as I may need to walk away for a bit.

This green plug/connector hangs loose and unused (currently, and as found) in the F700. Does anyone recognize it's functionality please?
(I do acknowledge that there are going to be commonalities with this harness and the light trucks...)

Thank you.

I just received this christmas present to myself:


Now hopefully I can make some sense of things.
The green plug with its 12 wires that started this thread seems to be named the "Hydra - Max monitor". What that means exactly is still anyones guess. I'll keep deciphering...anyone else who cares to shout out, please feel free.

EDIT: Okay apparently is has something to do with some optional equipment apparently not installed in my truck to monitor the hydraulic brakes.
If anyone has any equipment like this installed in their truck I'd be curious to see what it looks like.

 

check with a test light to see if any of those wires have power with key off,and key on

 

Good Morning,

Happy New Year to all. May everyone's pleasant wrenching continue to success.

At the moment, I'm losing a bit of enthusiasm.
Finally had to pull the dash out for better visibility and troubleshooting on that cooked wire that caused the mini mushroom cloud that day I brought home the fire truck. Red with Green stripe, the one that goes to the hydraulic brake monitor that is NOT installed in what appears more and more of a "base"-model truck that is this retired fire truck.
Well, one melted wire equals about five others damaged. Highly bummed. Now trust has further melted [har] for most of the wiring in this thing. As an aside, taking the dash apart, I am always amazed at all the sharp edges that are there to erode and work through the looms insulation over time. No wonder I had the shorts, plus all the additions the fire staff over the years did to it.

Sorry to ramble.

Now, very close to pulling the plug on it completely-pun intended-and purchase a kwik-wire package:

It is now well known to me that this F700 is, from the A-pillar to the B-pillar, basically an F-150 light truck.

I suppose my question is this (which I shall now research): How close do you think the F700's connectors at the firewall are going to correlate to an F-150's connections/connectors...?

This will help me specifiy the kit I order, and also temper my expectations...my essential concern is having to make in-the-field changes to a new kit, kind of defeats the purpose.

The thing about wiring -- circuits in general -- is that if it isn't completely 100% plug-n-play, then you have to research and understand every circuit/plug/connector/wire that you modify. There's a reason why wiring fires that barely damage anything else, cause insurance companies to total vehicles.

I can say from bitter experience just because a connector will mate doesn't mean it's wired to mate correctly [I'm thinking of an expensive Mitsubishi CRT monitor I was paid to repair about 25 years ago, and plugged a non-keyed connector into the wrong PCB. Expensive.]

I've repaired a few vehicle wiring mishaps brought to me over the years -- I'll never forget a fuel pump feed routed through the rear seat springs -- and unless the damage is entirely underhood, or entirely undercarriage, it's not often worth the effort involved if you have to pay someone else. If you can DIY, and have the will to do it, that's a different story.

Butchered/cut wiring doesn't bother me, but toasted wiring? Yeah, that takes out a loom, and that can be a lot of repair work, and it's easy to make a misteak. It can be done. You'd like to shortcut this using a harness for another model. If I were to do that, I'd want diagrams of both the donor truck and the patient truck, and tick off the connectors where the circuits match. I do not think that'd necessarily be an easier path the re-stringing a damaged loom, but you can assess the damage and I can't. I wish you luck.
