It would be close... I'd think close enough to work fine. Check the firewall plug though (bulkhead connector). You'll need the TSM wiring diagram for the 79 Spirit and a 79 CJ. The 79 AMC TSM has the bulkhead plug diagram, the wires are just labeled by connector position where the connector would be. I have a 74 Jeep diagram and it's close, so I think you would be okay, but some or all of the wiring positions might be different. All I'd think is you might have to lengthen a few wires, maybe the tail light wires. -------------- Date: Fri, 30 Mar 2012 23:40:28 +0000 (UTC) From:mccanada@xxxxxxxxxxx I was wondering if any one knows if a jeep 1979 V8 wiring harness would work on my sons Spirit V8 ? ?Are jeep wiring harnesses close to the same as the cars? -- Frank Swygert Editor - American Motors Cars Magazine www.amc-mag.com _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
