Not sure how to do a search for this....

1992 RS 305 TBI Driver side firewall between brake booster and fender. Small bracket holds relays for fan and fuel pump. On the front of the bracket, there is a flat connector that plugs into a flat THING that mounts on the front of the relay bracket.

In the pic, it's the THING that has a sticker that reads "BLH"

Name that THING!

 

I may be wrong but I think that is the hook up for your wiper motor.

 

That part is the electronic spark control module. Only used on tbi engines. most auto part stores carry them in stock.

 

White rider is right on the money, it's the ESC module.
If you are buying a new one, make sure you get the one for the 305 engine because each engine displacement uses a different ESC module.
