Hi. The real question isn't necessarily how to wire the Jeep- but more, what you intend it to finally become. Since you've decided to mate a CJ chassis with an M38 chassis it's never be one or the other. As per the previous questions the electrical portion is a bit complicated, unless you intend to just start over. Not easy, but less confusing. M38 wiring harnesses are expensive- about $500 for the main part of the harness- but the rest is even more so. Then there's the question of the motor- CJ or M38, with original (expensive) 24 volt equipment, as well as the fuel/vacuum pump, which not only pumps fuel but powers up the vacuum system, that mainly operates the wipers but also the ventilation of the sealed military distributor, that also houses the coil, that generates heat. Lots to learn about, and so I suggest you get the manuals for the M38 on CD from Military-Media.com, as listed below, and the much clearer paper reprint of the parts manual from Portrayal-Press, also listed below.
From one point of view, since the complete Jeep won't really be an original military vehicle, it might make economic sense to have a lookalike M38 on the outside but a CJ on the inside, as well as underneath. Whatever the disadvantages, it'll be less expensive, as CJ stuff- by comparison- is cheap & readily available, as a friend of mine often says. If you make your own harness, remember that all M-Series military vehicles had all black wiring, with stamped aluminum tags to identify each circuit. The circuit numbers can be found on Olive-Drab.com, and even easier by googling "M-Series circuit numbers". Having a harness in colors is a dead giveaway that it isn't original.
The path you've chosen isn't for the faint of heart, more for experienced hands, but whatever you decide, it's bound to be a real learning experience!
In any event, good luck with your project.
The dealers, etc. below are a resource, but start with the manuals.
