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.
