Hi I am troubleshooting my vacuum lines and I have found one but dont know where to connect it. It starts somewhere behind the engine block near the firewall and splits near the cruise control unit. one goes to the CCU and the other is not connected. Anyone know where this other end goes?
Thanks
Prem

Uh, what type of car? Carb, TBI, TPI, V6? Help us out here. For now the only advice I can give is to check the emissions/vacuum routing sticker on your hood, if it's still there.

Oops sorry the car in question here is a 87 GTA with 5.7 V8 TPI. I will look for the sticker. I feel something is missing.

Been awhile since I looked, but I think it goes (on my '89 IROC) up towards the driversdie fender to a vacuum reserve cannister for the cruise control.

Yeah, there should be a ball stuck up underneath your fender. Get on your back and look up, should be pretty obvious.
