Shouldn't be too hard. You can go thru the big firewall harness on the drivers side and find the wires for, coolant, oil pressure and tach. I can't remember how the Volt gauge works but I believe it comes thru the gauge power from the fuse box, not 100% sure on that

That shouldn't be a problem but you'd need a custom chip for it to run perfect
