I am looking at buying an engine harness from Year One - I have a 30% off coupon. I have a 383 and am wanting to run a late model alternator and will use the bracket kit from Andy at AR. The harnesses are made for a late model alternator or the standard alternator. Has anyone used one to know how the late model one wires up? I want to make sure I get the correct harness and am unsure of which one to get to run the later alternator. I was under the impression that the later alternators were "one-wire" but the one used with the kit Andy sells uses an adapter that has 3 wires. I've read the instructions but, again I'm unsure which harness to get. Not trying to be dumb I just want to make sure I get what I need the first time. Thanks in advance!
