'99 security anti theft issue, my fix

[Just call me Sean]

I got the truck from my uncle. Everything for the security system was changed, truck would still leave him stranded. I could have had the computer reburned without the security crap. Instead I got a '96 computer and the plugs for it at the junkyard for $20. I went through wiring diagrams and added the '96 plugs into the harness so I could use either computer if I ever have the original reburned. They are wired different so I did have to connect some wires to different plugs and I had to add power to the EGR circuit as it's fed individually on the '99. I don't have a gas gauge because the wire goes through the '99 computer and I wasn't sure if I could just hook the wire together to bypass the computer as it is on the '96. But it works.
