So I have a 92 lude that had an h23 non vtech motor. I stripped everything off the firewall for paint. I purchased a 93 lude with an H22. I swaped everything from the 93 h22 car including wiring except for the ABS hydrolic unit. They look exactly the same and my original one was much cleaner. I went to plug it in and the largest plug looks to be the same but there are a couple small tabs inside the plug that are different and I can plug it in.

I know that the Vtech calipers are bigger but I didn't think the ABS unit would be different. The wires are all the same colors and in the same pin locations. I could shave the plug so it fits but I would imagine I will have to swap the units themselves. Has anyone heard of this?

 

I checked http://www.hondaautomotiveparts.com and the part #s are the same betwen VTEC and Si models.

 

I found my problem incase anyone else makes this mistake. There are white caps inside of the connectors and one from the old ABS unit got stuck int he engine harness plug so it wouldn't plug into the new ABS unit. I was shocked that I looked it over very thoughly and didn't notice this the first time.
