Help me identify these parts
« on: March 31, 2017, 10:28:38 am »
There is 4 items coming out of my firewall that I cant figure out. The truck is a 86 and has been stripped of all emissions equipment. I am assuming that's what all of these are for? right by where the heater hoses come though. Can anybody help me out on these? Just starting a full build on this truck...needs LOTS of work. But trying to figure out what can be cleaned up and done away with.

Top is for the lockup torque convertor, bottom is the ESC plug in for the distributor.  I've never seen the tube coming out by the heater hose.  Last one, don't know.

Actually,the top one is the tip-in vacuum switch. The one for the lock up torque converter is around the 11 'o clock position above the brake booster

2nd that. Just pulled out my engine and I've got the same set up. I don't have the tube.
