Anybody know anything about swapping new hemi's in old mopars? I am using the factory computer and wiring harness, but am not sure about running aftermarket guages that I have. It looks to me like the factory sending units for oil pressure and water tempereture go through the computer. I am afraid that if I run the new sending units for VDO guages, it will tell the computer there is no oil pressure. Any help is appreciated.

Use the Mopar Performance crate computer and wiring harness. The stock computer will give you nothing but grief.

YOUR PCM WILL USE ONE SET OF SENDING UNITS AND THE GUAGES WILL USE A SEPERATE SET.I WOULDN'T USE THE FACTORY PCM EITHER,I'D PROBABLY USE AN AEM ENGINE MANAGEMENT SYSTEM.I HAVE SOME INFO ON MY SITE http://mysite.verizon.net/ls6ron/
