I traced the 3 splices and they don't seem to be part of my problem. The BLK/WHT ties directly to the ground bus in the fuse block. The pink wire goes to the TCC fuse and the GRN/WHT wire goes to pin 86 on relay 14 the FP relay. There's no question that these ARE NOT factory splices.
The BLK/WHT wire coming off the oil level switch is open to ground. I jumpered this wire to ground and it didn't fix anything. In the diagram above I can't figure out the transaxle range switch. There are two connectors on it. One is a 4 pin with YEL, GRY, WHT, BLK/WHT (which I assume to be line 27) The other plug has several big wires and other wires on it including a BLK/WHT which is grounded, so even though it's in a different connector, I assume this is the wire coming of the right side of the switch in the diagram going up to that junction point.
