Thanks very much for the support. Even though it would still be somewhat helpful if I was just talking to myself, just to get ideas together, the number of thread views tells me someone is reading everything ... <img src="/forums/images/graemlins/smile.gif" alt="" />

I (and others I am sure) would appreciate any info you can provide on that vacuum pump. Even though I plan on using the stock unit for now, if anything should fail it is always good to know about available alternatives, especially when dealing with custom vehicles built from rare parts.

Now -- on to another question. This one is for those who understand the QOS system.

As you all may know (have I mentioned this?), I plan on using the glow plug system from an 86 Troooper diesel. I bought what amounted to an entire wiring harness and all relays etc. - even the entire dashboard! - from a donor '86 truck. I believe I have almost all the pieces to make it work, with a possible exception: the 'sensing resistor'. Posted on my blog site (BLOG) are wiring diagrams from the 86 diesel manual and the 4JB1-T manual. They are identical, as far as I can tell, regarding the glow system (which is why I decided to adapt the '86).

The question: can anyone tell me what the 'sensing resistor' is? I've got all the other pieces, and am ready to connect the main power wire to the bar on the engine that supplies the plugs, but I've got a red and green wire left over coming from the controller that are supposed to go to this resistor. Does it go inline, between the plug bar and the main power feed from the relays?

Any insight, as usual, is much appreciated.

Ok, well I can't seem to get the images uploaded yet. I'll keep trying, so check back if need be...
