I had the same problem with the connector. It turns out if you look inside the connector there's a white plastic pin retainer that needs to be pushed back into the connector. (It's sticking out a little that stops the connector pushing on to the ABS connector) This had me baffed for a little while too.

The Rear block will only mount one way on the bracket as it has a locating pin on one side. The brake lines will only fit up one way.

Hope this helps.

Hi Mrsarit,

I would be very interested in your findings concerning the differences between the old and the new ABS system.
Would like to hear if the conversion is actually worth doing.

 

[mrsarit]

so I never know about old ABS
but I will report for new ABS.

1 & 2 are for the ABS Diagnostic tool I believe. (Just tape them to the Loom)

3 is Ground

4 & 5(not shown in photo) is 12V & Ground to be fitted into your old ABS 2 pin Connector (Orange) You will have to remove the Connector from your old ABS Unit with a small electronic screwdriver to release the Pins.

Hope this Helps

Thanks for the note. I was also able to confirm following the pin out that they are for the diagnostic tool.

ABS conv/ Larry or Chris please?

Early in this thread the attached pictures were posted showing the operational orientation of the prop valve. I'm doing my conv now and since i don't have anything to look at, I thought I'd just start by seeing what lines fit where (I can't believe I admitted that out loud). It looks to me like the two rear lines from the modulator come in the two bottom connections on the valve and come out the two top, both on the same sides, unlike the photo's posted earlier. Can you guys give me confirmation on that? And for my double check, at the firewall junction block, which line is which, RR and LR. Got 15 inches of snow the other day here in Ohio. It's surreal shoveling snow and then working on an NSX a few minutes later. Thanks!

Larry B says that nsxman2001 has done the conversion and it came out great. Maybe he has the answer.

Hi
This for pin 4&5

The connector that you see here is the power for the pump. There is a 40 amp fuse on the other end of the (+) wire so don't hook it up to the wrong thing. If you connect it to the wrong thing you will know because of the smoke that will come out.

I think you are correct.
The pictures above is wrong.
Now,I connect like this picture...

Thank Brad for your advice.

My NSX is 92 and old ABS modul have many problem.
so i change to newer ver.
Now,ABS is work and better than the old one (may be because of the old one is waste)

Thanks mrsarit! Ken, if you are there, we should delete the original email, it sure screwed me up.

That plug is for power coming from the harness on the car side. what I did was cut off the head of that plug and solder the two wires together with the two power wire on the New harness. Hope this helps

 

[goldNSX]

mrsarit, any updates? write-ups? :wink:

One question: What about the behaviour of the ABS LED in the dash. Does it light up while starting? What do you think was the hardest part?
Diagnostics: Is this usable in the NSX?

 

[goldNSX]

Maybe someone can help me out here.

Pic 1: Does this plug with the plastic looks ready to go or does it needs pushed back even more.

Pic 2: The 3rd plug from the left is the ABS module substitute which I've found under the glove box. But where goes the 2nd plug from the left goes to? It should be quite near to the ABS module but I didn't find it.

 

[Tanto2]

If it plug goes into the unit easily, it's OK. I didn't have to push mine much. BTW there are more posts for this thread as I don't see my posts on the harness intall. If you didn't know, you pull the orange lock collar up, push the plug in and then push the collar back down. Very slick. Seach for several more posts, and that layout above of the prop valve is WRONG!

 

[goldNSX]

Thanks for your help. This one http://www.nsxprime.com/forums/showthread.php?t=83018&page=2 also contains info about the conversion.

One question open. The white plug (not the one for the ABS control unit): where does it plug to?

nsxman2001 in the thread above wrote to this question:

The red plug goes into the new ABS Unit under the hood and white plugs you circled blue plugs into the orange plugs that your abs ECU is currently pluged into.. How that helped

So, does the ABS unit have two plugs? I only saw one of them.

 

[Tanto2]

I "think" the old ECU had two plugs, the abs unit has only one

My fault. I've found the ALB computer behind a big tube. It has two connectors. The first one I've 'found' was the one of the door lock.
