Re: EST wire help
Its a little wetherpack connector that should have black and tan wires going to it. Its located on the passenger's side of the engine bay between the strut mount and the firewall.

Re: EST wire help
is it just those two wires and if so all i have to do is unplug it. whats the difference if i leave it connected while timing it.
