I wouldn't touch your truck with a ten-foot pole. Your 98 engine requires a different ECM and wiring harness than your 93 truck. I shudder to think of the head-banging frustration of trying to cobble the two together. Far better to just trade up to the truck you want. gatliff User Jul 3, 2005, 6:22 AM Post #3 of 4 (2573 views) Re: 98 chevy 4.3 wiring Sign In Thank you I can get a 98 wiring harness with the computer if I need all this Tom Greenleaf Ultimate Carjunky / Moderator Jul 3, 2005, 7:53 AM Post #4 of 4 (2571 views) Re: 98 chevy 4.3 wiring Sign In Just my thoughts on this: You are opening "Pandora's Box" and will probably have endless headaches from this.
