WHats this plug connect to? FOund it under washer fluid tank

Looks like the DRL connector. It's not used on US vehicles (Canada started to require DRLs in 1990) so it has a weatherproof cap covering the connector (the cap should have a p/n F0EB-14A624-A. Normally it would be located inside the fender.
 
I have that plug on my 91... however my buddy's 89 does not .... what is the difference between those 2 years?.... Airbag! The connector acts like a spout connecting 3 cicuits and there are 3 airbag sensors.. I cut mine out the other day haven't noticed any adverse affects but the car is apart getting twin T04Es so I haven't driven it.
