if my calculations are correct its 75Hz 12V square wave to the cruise control and switch to the tach signal once enabled and then it should drive the engine up to 1500 and take over from there.

actually that sounds alright ... i will hit the wreckers tomorrow and see if i can find one ....

Get one from a VS since they are the older larger type like those in VN to VR and I know for a fact how they work and respond. I don't know how well the later small delphi units work, as with anything with these cars the older stuff is generally less restrained and more aggressive.

I reckon it should work well as the cruise control will pull the engine to high loads quick if the generator is loaded up a lot.

So people who are, or got, married are simple minded. As Aleksandr the meerkat says "simples".
