Need help please!!

I have a 86 with a 2.9 a4ld 4x4. It has a 89 computer on it to delete the egr. But I need help with the three codes it threw. Codes 95, 14, and 29. I know they are for the vss, fuel pump circuit, and erratic pip signal. Any help or advice on figuring these codes out would be greatly appreciated, no don't even know. Thanks.

Pull all your electrical connectors apart and clean them good with electrical cleaner and inspect good then put a dab of dielectric grease on them when you put them together. Disconnect the batt when doing this to reset the computer then when you run the KOEO test end the test when it starts giving you codes to erase the memory. Then run it for 20 minutes at medium speeds and run the codes while it is up to temp. Always fix the codes lowest number first erase the memory and reset the computer and then run the codes again to confirm any repair done.
