Redding Ridge Repair

I acquired a decent complete John Deere LX 255 with a bad motor and I have an LT 155 no deck or hood but with a good motor, the motors are the same but the electrics is definitely not plug and play, there is a bank of relays on the LT but not on the LX along with multiple plugs, wondering how complex the wiring would be, any help would be appreciated

John Deere D105 part out, transmission seems good, clutch has failed. Everything is available except motor and mower deck, message me if you are interested
