D6t LGP blade inop with codes

[mobile-tech]

they pulled the D6t outta the barn the other day .... blade inop , went up ,wont go down, now doesnt go up or down or tilt the side to side switch in operating . i started digging around found evidence of a mouse or 2 removed seat and side pannel and floor panels , found damaged wiring for operator seat switch, thinking with all those codes gotta have a damaged wire somewhere.. KSB01853
codes as follows
497-5
498-5
1078-3
1079-3
1197-5
1198-5
1078-4

well i replaced th chewed up harness 379-5603, started machine up same results blade inop those 4 active codes stile there, i unhooked Topcon piggy back harness at solnoid bank and plugged machine plugs direct into solnoids and started blade goes up , no tilt or down, then wont go up , codes go inactive at this point .
plug topcon harness back in codes go active

Attached are the diagnostics for all 4 Codes. I think I would test everything with the Topcon harness removed as a starting point and see what that throws up.

i proceeeded with sent dianostic information , i disconnected top con harness from solenoids and pluged machines plugs into corresponding solenoids ,the 4 codes went inactive . start machine blade raises and tilts if pressure is kept on joystick , if i let off and try and raise or tilt or lower sets codes( 1078-3) (1079-3) cycling ingnition switch yields same results it works, then stops and sets the two codes active ,cycle the igniton codes go back inactive
