ive got that wiring diagram but that doesnt help me. here is a pic of my cam sensor. as you can see, you cant see what color any of the wires are. i need to find out what colors they used to be so i can rewire them to a new connector.

The 3 wires clipped together that are black are the ground (G-) for the three pickups. Looking at the open face of the cam position sensor its shaped roughly like the letter D. Going clockwise starting at the 12 o'clock position the sensors are:G1 (red and black wires), NE (blue and black wires), G2 (yellow and black wires). You may want to check each pickup with a Ohm meter before going to any trouble to make sure they are within specification and not shorted or open. The specification is 140-180 Ohms for each pickup. The air gap between the pickups and the rotating tip is 0.008 - 0.016" (8 -16 thousandths of an inch). You'll need a feeler gauge to check it. If it checks out okay you'll need to interface it with the wiring harness and you said that you had no plug. Most auto stores including NAPA have the push connections that you can use. Here's a photo from the manual. You'll have to decide where to hack into the wiring where it's not rotten or cracked. If you cut anything inside the cam position sensor housing, slide off the woven insulation first to try and reuse it. Cut the wires staggered so that the soldered repairs don't lay next to each other to avoid shorting. Use silicone seal or heat shrink tubing to insulate. Slide the woven insulation back over before crimping on the push connection. Another thing to be aware of is that the oil seal in these can fail and that's a messy repair. During the time mine was leaking I put an aluminum foil "cup" under it to catch the drips. Good Luck.

so i took a closer look digging into it and found that when i took off black wraps that go around the wiring that i do have what looks like a red wire to going to one and a green going to another. i assume the green one would be blue. the problem is that i can't decipher either wire on g1, g2 has the green/blue wire and the NE has the red wire. that doesn't match up with what colors you said they should be :S from that diagrahm did you just figure out which pickup went to which location in the connector and crossed that with which color wire went where in the connector? i think i should probably rewire it with the colors that are on it but usually when people replay to posts they know what they are talking about. i just dont want to do it and it be wrong and have to redo it.

Youd be suprised to learn that people actually do post miss information intentionally. That page is a direct link to a creditable if not worshiped site.
You are right tho, the information you posted does not go hand in hand with the links data. I don't see what the problem is tho? just fallow the pins and hard solder them when your done. oh and take a more in focus picture. I really want to see what those wires look like.\

here give this a gander

Found this diagram here, not sure how reliable it is ?
