PCM and TAC box measurements

[thealien]

Like the title says I am looking for some measurements for the PCM and TAC box. I don't have my engine/harness yet but am trying to find mounting locations. Do you have to mount the PCM to a rubber mount or can I mount it right to the firewall or radiator support?

Thanks

The PCM mount is available from GM, you can get one of those and try your mounting out. If you are putting it under the hood (stock), and there would be a possibility for you to 4wheel or run hard I would do some rubber mounts. If you purchase your harness from some of the guys like Nelson, they can add enough wire to your harness to put it in the cab.

No room in the cab? Will not see much if any off road. More of a cruise vehicle. I have my PCM now. Its huge!

Yes they are a little large. I bought my PCM Mount from W Body Store
I think it was like $25.00. I will use it to mount to my inner fender on the DS, using rubber bushings of some kind, I havent gotten that far.

Thanks, I ordered one from the dealership. I'll let you know when it gets here.
