I did not have to do any work under the dash except for MS installation and battery relocation. I found it necessary to upgrade my ground wires and change some ground locations. The main part of the harness that usually runs over then trans on the frame is tucked through the wheel well. I relocated relays and other items under the cowl deleting the windshield wipers.
