Can any one tell me where i can locate these wires? Parking lights and the tachometer... I have a chiltons manual w/ the wiring diagrams, but I cant find them in the diagram. I am wiring up my remote start and alarm in my prelude and I was wondering exactly where i could locate them.

 

i cant remember, can anyone help out?

 

i know you can get to the tach wire under the hood......you can get at it either at the distributor (blue wire on the 2 wire clip) or at the service connector right near the battery.....

you could use an ohmmeter and then try all the guage cluster wires under the dash and find which one......

wait, i just had a better idea, check the chilton manual for the ecu pinout and find the tach wire at the ecu, thats probably easiest....

as far as the parking lights, the best i could say is maybe check around the fusebox....i have never dealt with them that much....

 

what year lude? I know on the 5th gens and most 96-2001 civics and such you can take out the insturment cluster and the tach wire is the blue wire back in there (sometimes it's easier to do that than go out and get the tach test wire under the hood, which is also blue and located near either the pass or drivers shock tower, depends on the year and stuff... but typically for prelude on the pass tower in a rubber "holder".. plug has spots for 2 pins but there is only one pin in it and the wire is blue).

Either way, to test the tach take a DMM and put it on AC. put one lead to the suspect wire, the other to ground. Start the car and see the voltage... now revv the car up slowly with the throttle body if you're under the hood, and the AC voltage should climb with the RPM's, and return to the original value when you let go of the throttle.

The other option for a tach is to tag a wire on the fuel injectors... I know they are a pain to get to atleast in the 5th with that plastic cover and all... but each injector has 2 wires, 1 wire on each injector will be the same color. This is the GROUND wire. The other wire on each injector is a different color, those are your "tach" signal wires and work fine for remote start setups.

As for the parking light I forget but check out techservices.codesystems.com. You might have to make an account (they email you your login but it's an automated system so you shouldn't have any issues)... or try this generic one if you don't feel like signing up...

oops sorry about the blank there!!. sleepy_vtec's lude is a 92.

 

ok, i got the tach wired in now. but i have to find a way to get my parking lights to flash when it locks and unlocks. Have any of you prelude guys ever put an alarm in? if so how did you wire for you lights to flash?
