Aircraft Spruce Ignition Wiring Harness Pirep wanted.

[Bob Martin]

I'm in the market to replace my 18yr old Slick ignition harness. I see that Spruce sells their own version harness, or marketed under their name. ACS's set is half the price of the Slick set yet appear to look very similar.
So I'm asking if anybody has used the ACS brand and liked them or disliked them for what reason? Slick=398 ACS= 188.

The other unknown issue is that ACS appears to sell only one PN for Lycoming engines P/N 12304-33 (Slick # M2363).
According to the Slick Application Chart my 0-360 A1A WD uses M4004.
I am not sure what the difference is between the two.

Any help with the decision would be appreciated, on costs alone the choice is a no brainer, but I don't won't to be penny wise and pound foolish.

The ACS one has pretty short wires. Can be a problem routing.

Seems like you have experienced exactly what I am trying to avoid.
Thanks for your reply.
