yup. it should look just like you had the lamp hooked up to a battery.

I use a high beam blub and socket.. not a sealed beam there to big and hard to work with.

Ok so I'm gonna have to play really dumb here for a sec. Where can you get one of these sockets and bulbs, and can you be a little more detailed about how to do it or do you have a link to a thread where you've explained it before?

andy read post 14.
were to get one.. any auto part store should have a basic connector for a 3 wire headlamp. if not find an old harness. then get a bulb that fits the connector.

Ok that's what I figured. But i'm more confused about how to set up the wiring.

andy its very simple and your over thinking this... well that and I suck at explaining stuff.
in your case unplug the maf and unplug the pcm connector that goes to the map (iirc its the body harness) then go to the correct pcm pin and hook that pin to ground. next go the corasponding maf sensor pin and hook up one side of the lamp to it and the other side to ground.
one catch is you need to isolate the circuit correctly or damage may result.

You mean to 12V power? Both sides of the lamp to ground wouldn't produce anything...

Yeah I was thinking that way...or hooking one side of the lamp to one pin on the MAF sensor and another side of the lamp to another pin on the MAF sensor, then the corresponding pins on the PCM end to ground and 12V. If you had a bunch of wires to test, this would be a little faster because it would test 2 wires at once...but since only 4 wires even go to the PCM from the MAF sensor then your way would be much better and less likely to screw anything up...trying to do 2 wires at once might get confusing and risky to put 12V on the wrong wire :/

andy I do loop the circuits at the shop to do more then one wire on things like injecotr harness and what not. was tring to keep it simple for anyone that may come along later and only read part of it.
testing in this manner is more accurate then a dvom for the simple reason that a single strand in a multistrand wire can carry enugh to pass a resistance test.. ive even had a few with broken stands pass a test light. But a high beam needs a lot more to work.

Ok so I have a spare halogen that I could use...would that work or do I need a high beam bulb? And also...according to whoever looks at my numbers from backprobing the MAF sensor, everything looks pretty good. Or at least that's whey they said...
