How do I tell I if my 94 hatch has abs

http://thisoldhonda.org/vindecoder.php you can use that, or there should be a box like thing with metal lines coming out of the top attached to your firewall. Mines deleted or i would show you a pic.

Would it be OK if u used a non abs master cylinder?

No, not at all, you NEED an abs booster and cylinder for an ABS system........too bad I already ripped mine out and threw it all away

if you have orange connectors in your engine bay on the passnger side. you have abs. easiest visual i can tell you lol. but if its a 94 hatch and its not an Si and you are from the USA more than likely you wont have it.
