So I am sitting here with wiring diagrams for the M715 all over my table. Why did this seem easier when I did this for Todds (fishermans) truck way back when. 2008ish

Well God Bless the search function. Lookie here...
From 2008

This is al kaiserjeeps not todd. I could have fun with this...

Todd and I stayed up late and I did some testing in the 3 lever light switch to see which pins were active on which setting. I am trying to incorporate the stock switch into his new wiring harness. This is what we found...
Pin F is always incoming hot. Changing the switch levers routes power to the pins in this manner.

Stoplight / off pins A,J
Stoplight / dim pins B,J,A
Panel bright setting is the same pins as dim
Stoplight / park pins B,J,A

Service drive / Off Pins M,H,J,A
Service drive / Dim Pins M,B,H,J,A
panel bright setting is the same pins as dim
Servive drive / park Pins B,H,J,A

BO marker / off Pins E,A
BO marker / dim pins E,B,A
panel bright setting is the same pins as dim
BO marker / park pins E,B,a

BO drive / off pins E,D,A
BO drive / dim pins E,D,B,A
panel bright setting is the same pins as dim
BO drive / park pins E,D,B,A

This should be most settings. We needed to document this to incorporate his new harness into the 3 lever switch. Add a couple wires and we will have a modern fused harness with all the black out functions. The manuals can be vague on what bulb is on by description. Now we know what pins get power. Pictures will follow. I don't have my cord from camera to computer here. I'll post up when I get home. Hope this helps someone in the future.
Back to burning the midnight oil...

AND

LOL... I dunno about Todd but my hands hurt. What a cool project. I think we have about 155 hours, 5 weekends, 4 pizza's, 18 packs of cigarettes, close to 4 gallons of coffee, 2 cans of whip cream, 5 mocha's, 4 propane torch refills, approx 30 wood pellet bags, and two visitor's into a completing an 18 circuit wire install in tandem with all the BO marker lighting, distribution box, etc. There were a couple of serious curve balls that took time and troubleshooting to sort out. The first we (I) should have caught sooner was attempting to figure out and wire the wrong turn signal switch. Once that was discovered it was quick to figure out. Then we had a different relay set up for the headlights and horn than intended. The wiring diagram we had was wrong so when the truck was powered up with the 3 lever in off one headlight would light and the low horn would sound. Nothing is supposed to power up in off position. Found the issue and changed the wiring so it works great now with the relays that are installed. Lastly it looks like the wrong bulbs are installed as they are what look like a European type bulb that lights both low and high on the bright setting. We here in the states have mostly either a low or high beam only on older stuff. So the bulbs were back feeding around 5-6 volts into the low beam circuit when brighted. A big leak so to speak.

The headlight issue had me stumped and I could not go to bed. After figuring it out and changing the wiring to make it function right I had worked for 19 hours straight. Talk about living dead.

I am now home and I plan on sleeping for two days straight.


I thought Todd was going to spontaneously combust when it fired. It was turn key and just idled like it was just shut off yesterday.

I have real nice pictures and a short video of the truck pulling out of the shop. I'll post up when I wake up.

Lots for me to review. Every little bit of info helps.
