Here's a quick write-up i wrote for a 94-96 EL gauge cluster installation into a 92-93 Honda Prelude using the 92-93 dash harness.

This is the pin/wire write-up that I used for the conversion. The numbers on the left are the pin # on the harness connectors (from left to right). The colors are the wires that you will need to attach to the corresponding pin #. The descriptions of most of the wires are also shown.

Harness H - (10-pin connector; I used the green 10-pin connector from my stock 93 dash harness that connected to the bottom left of the original gauge cluster)

1. Yellow -- power
2. Pink -- speedometer
3. Yellow -- power
4. Red/Black -- dimmer wire
5. Black -- ground
6. Orange
7. No wire
8. Light green (you need to splice the wire from the dash clock harness & run it to the pin) -- trip mileage memory
9. No wire
10. No wire


Harness J - (5-pin connector found on most Honda power window connector harnesses, but since only two wires are needed to be connected, I used a 2-pin connector from a computer motherboard fan)

1. No wire
2. No wire
3. No wire
4. Green/yellow -- right blinker
5. Red/blue -- high beam


Harness M - (5-pin connector; I used the yellow 5-pin connector from my 93 stock dash harness that connected to the top of the original gauge cluster)

1. Blue/silver spots -- tachometer
2. Black -- ground
3. Red/yellow -- high beam
4. Green/blue -- left blinker
5. Blue -- SRS

When you're looking at the EL gauges from the back/top, there are 5 connector plugs (harness H, I, J, K, L, M from left to right). This is also a connector plug on the bottom left (when facing the front of the cluster), but you won't be attaching anything to it. Harness K and L are connected to the inverter so we won't be dealing with those harnesses.

(Note: Some of the pin holes on the connectors had some missing wires so I manually shoved a piece of wire into those missing wire pin holes. There as better ways of doing this such as removing pins (with wires) from an unused connector plug and connecting those to the corresponding spots that are missing pins.


Needed:
- 94-96 EL gauge cluster assembly (including inverter and harness that connects
the inverter to the EL gauge cluster)
- 2-pin female connector (I cut one off from a motherboard computer fan)
- LOTS of wire (I bought red 12V wire from Wal-Mart)
- wire cutter/stripper
- Electrical tape
- Soldering Iron
- Solder

1. Begin by removing the gauge cluster and the instrument panel (fuel/temp gauge) so you can have access to the dash wiring harness.

2. There are three connectors that plug into the original gauge cluster. (When facing front of gauges, ones on the bottom left, ones at the top and the 3rd connector is on the bottom right of the gauge cluster. Cut these 3 connectors off, making sure to leave about 3-4 inches of wiring on each plug. Out of these 3 plugs, you'll only be using the green 10-pin (pins are on one row) and the yellow 5-pin connector (pins are on one row). You won't need the other connector (it was a green connector that was connected to the bottom right part of the gauge cluster).

3. Take you're wire cutter/stripper and strip about 3/4 of an inch off the ends of each wire. Now take the wire (you bought from Wal-Mart) and solder about a 1 foot long piece to each wire on the dash harness then cover each solder connection with electrical tape.

4. Now connect the corresponding wire colors to their designated pins listed above. (Note: there are 3 yellow dash wires but you'll only need 2 so I just wrapped electrical tape around the extra yellow wire making sure the wire isn't exposed. This will be the same case with the black wires (3 dash wires but only 2 needed) so cover the extra black wire with electrical tape. Also, you have an extra wire (red) from the dash harness that’s not needed in the install so wrap that wire in electrical tape.

5. Finally, attach the 3 connector harnesses into the EL gauge cluster and then turn on your car to test to see if they work. The only problem that I, along with many others having is that the trip meter resets every time I start the car. In the wiring diagram (harness H, pin number 8) it says to attach “light green” wire to pin 8 on this harness which keeps stores the trip meter in memory. Well, I looked at the electrical diagram of from a 1993 Honda Prelude and it appears to be the “yellow/white” wire from the dash clock wiring harness is the wire that keeps the “time” in memory (constant 12v wire). I tried attaching this “yellow/white” wire (opposed to the “light green” wire the diagram mentioned) to pin 8 on harness H and still no luck. If anyone knows how to sold this problem or if anyone has the dash wiring diagram from the 94-96 Preludes (that includes which color wires go where), please post it here. Thanks

 

great write up
do you have pics of the material needed and pic after installation?

 

This should be in FAQ 4 sure!

 

damn you need pictures

edit: this thread is 4 months old, lol.

 

i got a el dash harness with invertor

wont need to wire anything jus plug it in

200 bux obo shipped

 

i forgot 2 picture the harness that goes from the invertor to the cluster but I DO HAVE IT AND WILL BE INCLUDED
