Outside the box Jeep electrical question

OK. I'll try to keep this short. For almost 2 years now my 1994 Cherokee 4.0 automatic has had this unfixable problem involving the throttle position sensor. Basically the Jeep drive just fine and smoothly but once you drive 10-15 minutes in the city or drive the highway and come to a stop off the first exit the "check engine" light pops on and the Jeep starts idling erratically, surging, etc and when you check the trouble codes it shows a code 24 TPS. Replaced the TPS multiple times as well as the plug and a good length of the wires plus replaced other related sensors. Still the same problem. NOW here is my odd question. Can anyone think of any connection at all between what I`ve just described and/or the wiring involved AND the windshield washer fluid level warning light on the dash? Recently when I changed the crank position sensor and oxygen sensor I noticed that the "Low washer fluid" light on the dash went out for the first time in a year (It was always on even when the fluid was full).. That struck me as odd but then I noticed that my "check engine" light problem went away for 3-4 days. I figured that I had cured it but then today it (Check engine light) popped back on and simultaneously the "Low washer fluid" light came back on. Can anyone think of any twisted way that these two things can somehow be connected?... Maybe a shared wire harness somewhere which could have gotten pinched?...I`ll nose around Saturday but until then I was hoping someone might have some wild idea to try.

I would first think ground theft. How good is the mesh cable that runs from the rear of the engine up tot he firewall? When that goes bad or the battery to body ground goes bad, strange things happen because other things find alternate routes to ground.

There is also a ground center near the dipstick hold down bolt on the engine block I think.
