I have the Y1/M&H harness and agree it is a good harness. There are lots of choices for non-stock harness but not much stock replacement. I used the M&H harness to re-do my mostly engine compartment, mostly stock instrument panel and wiring and modified it somewhat for high current alternator and EFI. I was glad to have all the stock bits including pass compartment and instrument cluster referenced to the stock wiring diagrams.
