Wiring issue - Honda Prelude Forum

zmaher001 · 07-05-2009, 09:02 AM

Ok i bought a shell of a 93 5spd and swaped my h22a and h23 tranny into it (well the shop did rather). The main harness wiring under the dash and such was a complete disaster so i swapped the main harness from my 92 auto chassis which had the h22a in it before the swap. I turned the key and there was nothing. Now i know the 2 clutch pedal switches need wired up and some other things need addressed but i have used the search function and came up with multiple answers but not one definitive answer. SO if any guys that have done the auto to manual swaps on a 4th gen could help me out that would be great thank you

was the 92 auto harness pre-modified for a manual?
if it wasn't, you will have to go through this write-up for the wiring changes. I did not do the wiring changes because my harness was from a manual car.

Cut open the transmission wiring harness. Cut off both counter shaft speed sensor

connectors, the torque lock-up connector, and up/down shift connector. Leave the

torque lock-up wires (yellow and green/black) exposed and re-tape the harness. These wires will be hooked

up to the reverse light switch on the transmission later. In the passenger side kick panel, seperate the red/white and white/black wires from

the connector that went to the Transmission Control Module. Extend these wires

to the auto shifter harness and hook them to the yellow and green/black wires. Connect the red/white wire to

the yellow and the white/black wire to the green/black for the reverse lights. Re-install passenger side kick

panel. Unplug both clutch switch connectors from the assembly. Connect both solid black wires together, extend them and connect to the

black wire in the shifter harness. Extend the black/pink wire and connect to the pink wire in the shifter harness. Extend the black/green wire

to the shifter harness and install a female spade connector to the end of it. Connect this wire to terminal 86 on a 30amp relay. Cut the

connector off of the big black/white and black/red wires that are beside the shifter harness. Install a female spade to the end of the

black/red wire and hook it to terminal 87 on the relay. Install a female spade to the end of the black/white wire and add a 6 inch section of

wire in with it. Connect the black/white wire to terminal 30 on the relay. Install a female spade on the

6 inch section of wire and connect to terminal 85 on the relay.

so if you turn the key and there is nothing, it could be that the transmission safety switch is not switching correctly when you press the clutch pedal in. You said you didn't use the relay so this could be the problem

if you turn the key and everything lights up, but no turn.....it's the clutch interlock switch
