Anyone have a good wiring diagram to install an M151 heater into an M37?
I was on Cabell's website, and he has a diagram listed but the components in the diagram differ slightly from what I have. Cabell also has a photo of the wiring he used and I bought the same, trouble is I do not know where to hook up the hot wire, and Cabell's photo shows the breaker not hooked into the line at all. The wiring diagram listed shows a different resistor altogether from mine, and shows the wiring hooked into the instrument panel somehow. Color me confused. Any help appreciated.
Need M151 heater wiring diagram.....

Nick, I have several M151 direct support/general support maintenance manuals which should have the info you are looking for and will see what I can find tomorrow and let you know what I am able to locate. I don't have time to dig them out tonight, I have KP duty

Manuals

Thanks, I appreciate that.

I checked the three manuals I have and none show the wiring for the heater, only the standard diagrams for the 60 and 100 amp. systems and not not the heater specifically although they do have heater install info and drawings.

Sorry Nick, I thought I could help but no luck.

Install Manual
This may not help as it isn't for the Mutt, but here's a link to the M37 fender-mounted heater & defrost install manual.

You can trust your mother, but you can't trust your ground.

i have a pic that shows the wiring from the installation manual for the M-151 heater. I can scan it and e-mail it to you if you want or try to describe it here.
Let me know.
