Visually inspect the electronics on the engines. Do they look the same?

No this is why I am changing engine harness and all. I was just wondering if the harness will plug directly into the existing wiring on the fire wall or will I have to replace all the wiring? Thanks for the response.

Just swap the blocks if possible. The heads and up are different. The 98 heads will bolt on fine but the 95 intake won't bolt onto them. Your harness isn't at all compatable. Also the 98 engine requires 55psi fuel pressure and the 95 pump only puts out 13ish. If you ask me the swap isn't worth it. To make it work u need a new pump, the ecu and harness from the 98. The 98 transmission as well (electronics are different). And it's gonna be hit or miss with the instrument panel functioning.

I have the complete 98 truck here that runs perfect less than 100k on it but is totaled. So if I change the ecu and fuel pump would it work? I was going to put the complete drivetrain under the 95 from engine to rear end with ecu and all, but wasnt sure about how the wiring for the drive train would be with the all the inside wiring and components. the dash is the same the only difference is the 98 has pass. side air bag and the 95 only drivers side

Would the harness where it pugs in at the firewall plug into the 95

Idk all you can do is try it. The have the same dash but the 95 is still obd1 where the 98 is obd2. I belive the ecu is under the hood on the 98 and the 95 has it under the dash. Being that way there will be wires going different places between the two. Anything is possible with enough effort.

I dont think it will,the wires are different colors. I'm having the same problem except mine are 1500,not the z71. I have no idea when it comes to the schematics of each of them and how to wire them under the dash
