so not sure how many people on here use autozone.com's repair section but i tend to use it a lot for random refrence materials...
i have a 91 hatch with a z6 that i was wiring up this weekend, so i went to autozone.com and printed out a pic of the ecu wiring...
well, what i found out is that auto zone's info is off, or inaccurate, in the following way
most honda people use the plug numbering as follows...
obd1 A plug has 26 pinouts...
25 23 21 19 17 15 13 11 9 7 5 3 1
26 24 22 20 18 16 14 12 10 8 6 4 2
well when i refrenced auto zone it said the vtec solonoid goes to pin A15 and the vtec oil pressure goes to pin D14
the proper wiring is A4 and D6
so autozone's pinouts use the following system
13 12 11 10 9 8 7 6 5 4 3 2 1
26 25 24 23 22 21 20 19 18 17 16 15 14
so autozone's A15 is honda's A4
and autozone's D14 is honda D6...
so if you ever refrence directly to the wiring diagrams keep this in mind...
i could not for the life of me figure out why the pinouts i needed to use already had wires in them...
so i ended up getting my hatch to run with no check engine lights, no road test yet as i finished up the wiring late last night..
