Hello everyone...new guy here with a question. i just bought an 88 TC w/automatic. she's been sitting for awhile but i got her running. Here is the problem though. it wasnt getting any boost so i started going through the engine bay and i found the vacuum tee underneath the intercooler on the turbo housing to be broken......the vacuum hoses had dry rotted and 1 port on the vacuum block itsself(the one that goes to the switch on the firewall) has completely rusted away. my question is what is the switch on the firewall for and can i just plug that port and reroute the vacuum hose at another source? i tried to make something at the hardware store but i cant find anything to replicate the fitting. thanks for any help.
