I got a donor truck. 2005 tahoe with a 5.3 in it. Plan on pulling it out and installing it in a 98 silverado with a 4.3 v-6. I know it a lot of work. Question is. Is it better to get a stand alone harness for this being the computer programming. Obviously the components are gonna be different such as alternator, power steering pump, ac compressor are wired different. Probably gonna use the 05 trans too. Any insite or suggestions before we dive in like mad scientist. Thanks.
