    91 Deville Distributor Coil wiring diagram

    have a 91 Deville with the 4.9L engine. I had an E41 error code, (Camshaft Position Sensor or Circuit error). I removed the sensor and tested it the way the manual said. It was good but some of the plastic plugs from the wiring harness disintegrated. I got a new OEM GM for $98 and replaced it but I didn't take a picture before disassembling it or sketching a diagram. I was able to connect all the other wiring plugs but there is another wiring harness that has a 3 plug connector on 1 end that connects to the coil and the other end goes inside the distributor. It has a 2 wire plug that connects to one side of the ignition module and a strap with a chip on it that bolts to the bottom of the body inside the distributor. There is one more red wire with a female spade plug that also goes inside the body that I can't remember where it connects to. This is comming from the B+ coil plug as shown on the coil cover. I can't find any other male spade connectors to connect it to and my Hayes manuals pictures don't show where it connects. It shows the wire but it goes to the edge of the picture and is cut off. I tried google image and a few other places but I can't find a picture showing it's connection. Any help would be appreciated. I can't put the distributor back together until I find where it goes.

    Thanks, Morgan
