Yeah, I can get a korean glow relay pretty cheap. The guys that installed my engine also did a gasser w140 to 603 swap, they say they used an electric vacuum thingy, (I think it's the overboost solenoid) to make a shut off system.
I'm not sure about the alternator, but the power steering pump mounting is different, and the compressor is a bit too long. I'm going to use the accessories that came with the engine. The power steering is hooked up already and is working just fine. Still gotta check the compressor. The alternator is probably fine too, easy to refurb.
I plan on using a gauge cluster off a 124, gutting the innards and placing them on the 140 cluster. Haven't gotten there yet but I may be able to re-use the 140 gauge faces and lighting. Calibration may be off but as long as the gauges move.
Any suggestions about the gauge cluster? ALL the modules on the passenger side have been removed. So anything that has to do with them is pretty much never going to be utilized.
Surprisingly the modules in the fuse box still work. (headlamp and wiper modules) The only thing that got trashed was the aux fan relay and the convenience module in the trunk, and of course the 2 seat control modules.
Thanks for the link, will read up on it.
