Re: 89 GMC Cummins conversion

On the firewall you can see the external voltage regulator that I merely unplugged after putting in the internal VR. This picture is about 3 years old and I have since removed it from the firewall. The mechanic that did this install back in 2000 never even tried to reduce the wiring under the hood.

Getting the exhaust system finished up later this week as well.
