TerryS,

Thanks for the info! I am using one of Jim's adapters to fit a 616 in my 1967 88. After this works out, I'm tooling with the idea of putting a 617 in my dead 1994 5 speed disco. It's just begging for a diesel transplant!

Any leads where to get such a solenoid operated valve? Sounds like exactly what I need. Jim recommended some kind of switch from McMaster Car, and I thought that's what he might be talking about... he's using some kind of switch on his 88 set-up. I'll get with him again and get some more details.

Thanks again
