In another effort to become familiar with my engine and how it's all wired together, I see a couple components that I can't find on any wiring diagram or I have questions about.
1. 15amp fuse on the aft engine harness. I see the 20amp fuse for the TKS module.
2. Relay off the harness behind the carb. Has Yel/Blk, Yel/Red, Blk, Red/Pur. I understand that that the Yel/Red is the starter line and it probably energizes the relay. This would seem to then power the Yel/Blk from the Red/Pur but I can't seem to find where the Yel/Blk wire goes.
3. Tan/Blu from a sensor on the aft part of the intake manifold. I'm thinking this is the overtemp alarm switch.
4. I see the oil press switch (Pur and Pur/Yel) for the TKS circuit and oil pressure sender (right side looking aft), but where is the oil press switch with the Tan/Blu wire for the low oil press alarm? Is there one? And also there is the Tan/Blu wire from the ICM.
Looking at the TKS wiring diagram, it would seem that if the TKS oil press switch opens, power to the fuel pump would be cut. These seems like an auto engine off if oil pressure is lost.
