I have Alldata but anything older than 1982 is asking for a disk.. I'm working on some of the wiring and this has a high idle solenoid constantly energized keeping up the idle.. I can just unplug it, but curiosity has me wanting to know what controls this.. Does anyone have an Alldata disk for this? No number shows up, it just states to insert 1978 Ford truck emissions disk.. Thanks in advance for any help... Tek1229

The Alldata emissions disc has no wiring diagrams. You need to find Mitchell Vintage wiring. I think it is on DK somewhere.
