[roy13]

ok i dont have a pic i wished i did but theres a tiny wire coming off the main harness i tthink..its right behind the plenum comes of the other wires making it like 3 inches i just cant find out were it goes?it looks like it plugs on a sending unit or something its more towards the passenger side ..also got it crunk today an i got no spark on # 2 (1st coil or injector on drivers side) tried switching coils an plugs around but staying in the same spot i havent tried to change injector any ideas on that to?

Take a picture and upload it using photobucket.com

Does the wire have plug on the end of it? If it does it has to go somewhere... Regardless it's only long enough to go where it needs to. Just move it around and see where it will reach to.

yea its only about 3 inches an it looks as if it would plug to a sending unit..like down on a tiny stud just caps over it

If it is only 3 inches long then it has to plug into something 3 inches away. Problem solved.

Doubtful. Take a few pictures of it so we know what you're talking about.
