Well John
I can only give you some second hand info. The injectors are hi impedance, the oil pressure sensors are the same, the water temp. sensor may vary in style depending on the type of intake manifold (probably same reading value) AIT may vary in style, MAP may vary in style, all of the "variables" are due to the different model of engines ,marine, snowmobile, off road, ect ect. ignition coils are the same. cam sensors are the same , crankshaft timing sensors are the same. As I recall the "critical" set ups are the timing of the injectors and the choice of ignition coil arrangement, but the instructions are very detailed and clear. If I can find my instruction book I will photo copy it and snail mail it to you (IF--- I can find it).
Randy at Watcon is trying to make up some specs for us on these very items and carry them in stock where possible. As I said earlier he is also in the process of making up "pigtail" adapters that have the correct plugs on them that can be soldered/connected to what ever harness we make up. There may be two different length or maybe one length and you cut to fit. He has no price for the kit yet but is working on that also. I think he will only sell the adapter made up rather than just a connector/plug because he has the proper tool for making the leads and does not want poor adapters made up using the wrong crimping tool, like a pair of pliers and a hammer !!
He is really bending over backwards to help us since he is really interested in this engine. It all just takes time.
