The 2nd auto cont. just went out on my 84 Sub. I've got a jumper wire ran into the truck to ground and make it work for a temp. solution. But I'm thinking about doing the manual control thing. I'm putting on new head gasket's at the moment so it would be a good time to do it. I think I'm going to have to rebuild or replace the motor in the nere future though, has a BIG ring ridge and some crumy looking cylnder wall's. I just need some info on what I need to convert. Anyone have any pics or wiring diagram's? What glow plugs would be a good choice for a manual set up?
