OK now I'm understanding you!
The wire in question should be blue. The coil looking thingy, is the electric choke. The large item on the tee, is the oil pressure sensor, & the smaller one is the sender switch. Basically these things on the tee want to see oil before anything else down the line will work.
Some of these things should be left intact when doing the nutter.
EGR, manifold heater, it's sender (green wire) behind carb, the diode card in the plastic box next to the battery, & those two relays there are for the intake heater & the electric choke. One towards the back, should be for the choke, It may be worth looking at as the possible cause of the burnt blue wire.
