I installed them in my 92 and had to do a little modification. since I swapped in the 94+ interior, I had the switch down on the console but the stock harness is behind the tweeter. if you have a 92-93 switch then you can just hook it up to the green plug behind the tweeter. if you have the 94 switch then you can do what I did:
for the brown 4-wire connector under the dash (relay connector), you can either hook up the relay harness that comes with the fogs, or if you don't have that (which I didn't) you can try to find a honda relay at the junk yard that will fit into the socket. luckily I was able to use a relay from an acura cl that I got some parts off of, but I figured out what each wire was for just in case:
BLU/RED = connects to switch in relay
RED/GRN = connects to switch in relay
RED/YEL (2 of em) = connects to coil in relay
if you have to use a generic relay you could use those wire colors to hook it up.
as for the green switch connector behind the tweeter (you'll have to dig to find it), I tapped into the wires and ran extensions down to my switch on the console. I didn't have a connector for the 94 switch socket so I used a floppy drive power plug from my old computer's power supply (the smaller of the 2 types). the wire colors on it were [YEL,BLK,BLK,RED]. since there were only 3 wires that needed to be hooked up I snipped off the black wire closest to the yellow one so it ended up being [YEL,(cut),BLK,RED]. then I connected the following wires from the green connector behind the tweeter:
RED/GRN -> RED on floppy harness (+12v for illumination on switch)
BLK -> YEL on floppy harness (illumination ground, switch ground)
RED/YEL -> BLK on floppy harness (+12v for switch)
the floppy plug works pretty good, it fits in there pretty snug and will only fit properly in the right direction, so it would be hard to reverse the wires.
sorry, that was kind of a long answer to your question.
