You would have to have the engine and transmission wiring harness and fuel pump harness. And you would have to install an electric fuel pump that will pump No lower then 9 LBS. and NO higher then 13 LBS. in the fuel tank. You will also have to get and install a ECM / ENGINE CONTROL MODULE / COMPUTER IN THE TRUCK. Basically you will need alll the ELECTRONICS FROM the 1994 and install all of it in the 85 truck and you will have a NICE ride. GOOD LUCK
