Help! Wiring a TD-60U OBD1 distributor to 5th gen Prelude h22a

I searched and found a post by "Bustr" on how to wire an OBD1 distributor to h22a swapped 5th gen prelude but the distributor he used does not match what I have in my hand (TD-60U).

I swapped the h22a4 on my 97 prelude to a h22a motor that came fitted with a TD-60U distributor with external MSD coil wired to it. The guy I bought the engine from was using it on a civic eg.

My engine harness is original OBD2 that came with 97 prelude and I am using P28 ecu with OBD1 to OBD2 conversion harness hooked up to it.

Since I can't use my OBD2 distributor I need help figuring out how to wire this TD-60U OBD1 distributor to my 5th gen wiring harness. The h22a does not have the oil pump swapped so all the ckp, tdc and other sensor need to be wired to this distributor.

Anyone has a write-up or could point me to right direction?

Distributor has two plugs. One is a two wire plug and the other 7 wire.

The 7 wire plug has:
1) white with green stripe
2) solid green
3) Pink? with green stripe
4) Solid Pink?
5) nothing
6) Green with white stripe
7) White with green stripe
8) Solid White

Re: Help! Wiring a TD-60U OBD1 distributor to 5th gen Prelude h22a

To point you in the right direction, it should be a simple wiring job. The hard part is doing the research.

Download a 5th gen, and a 4th gen service manual. Find the wiring for the distributors. And cut and rewire how they should be in your wiring. That's if your just talking about the wiring job. It's just as simple as hooking up an aftermarket radio. Each wire has a different purpose but the colors don't match with 2 seperate applications.

But if you need more info on the obd2 to obd1 swap there is tons of info all over the internet, like here, honda tech, prelude power, just google it. You will find tons of info, dig through threads and find the info you need. If you still can't find it maybe someone else can help. Good luck

Oh don't hardware the wires though. Use the harnesses still

I too have been looking for a good write up on how to do this. The one bit of light I can shed on the matter and the course I will probably take is to buy the adapter harness from rywire. Its $60 shipped and all plug and play, they have options for internal and external coil distributor.

Thanks bigblue. At least this will get me going. I found the exact link for anyone else looking for it in future. I think by the time I buy the used harness plugs, wires, time spent figuring it out, I am better off buying this harness to make it look nice and professional.

Re: 5th gen Prelude h22a no spark

Ok I still don't have spark after hooking up the RyWire OBD2 to OBD1 harness for ckp, tdc sensors to OBD1 Distributor.

What should I look for next?

Re: Help! Wiring a TD-60U OBD1 distributor to 5th gen Prelude h22a

Yes, I saw that. I ended up buying Rywire OBD2 to OBD1 distributor harness as shown above but still couldn't get any spark. I noticed one thing in Bustr thread that he talked about 8-pin connector and there is a Blue wire for crank position. I have the TD-60U distributor with only 7 wires. Could that be the issue?

Do I need a TD-61U with 8 pins?

Re: Help! Wiring a TD-60U OBD1 distributor to 5th gen Prelude h22a

Sounds like the TD-60U is correct for an JDM H22a.

The blue wire should be on the 2P connector right? With blk/ylw?
It looks like there's alotta confusion w/ that blue wire, whether its the CKP or tach signal.

Some more threads;
Obd2a to Obd1 Distributor Wiring Diagram? - Honda-Tech


DIY -- Obd1 to Obd2 Distributor Conversion Harness - Honda-Tech
Than the last post in this thread is claiming the CYP and CKP are actually switched...

Did you get the appropriate harness for your distributor? They make one for internal and external coil. Your car should be setup for external coil. I found another link that may help shed some light on what to do Honda Prelude H22 USDM to JDM Distributor wiring.

Yes I got the right one (External coil). I don't think there is a difference other than they send you a small wire to jump the plug that went into OBD2 coil.

I kind of gave up on this issue due to the cold weather in Ohio. Taking the car to dyno shop Monday to have them figure it out and eventually tune the car.

Re: Help! Wiring a TD-60U OBD1 distributor to 5th gen Prelude h22a

Figured out the spark issue it turned out the ICM (small unit inside) was bad on the OBD-I distributor. I swapped the ICM from the OBD-II distributor and I had a spark in all four plugs.

Car still didn't start though so took it to a reputable Honda tuning shop for diagnosis.
