Understand from their diagnostic guide, that applying B+ to this terminal should result in powering the Fuel Pump. Should tell me if the relay is bad. But the Tech Manual doesn't mention where the terminal is located.
It should be a red wire. Heres a pic http://www.mhtc.net/~jbomkamp/fuelprime.jpg
The top of the pic is the engine firewall and at the bottom right is the underhood fuse/relay center
