On the back of the firewall in the engine bay, center of firewall near the top, are three relay looking things.....2 gray and 1 black. What are these?

They are right underneath the cruise control module in the engine bay. My injectors are getting power, but not pulsing. The main wiring harness runs through/into these things. Im wondering if one controls the pulsing of the fuel injectors.

Ill try to post some pics.

this last pic is of a black box that sits above the "relays", in between the wiper motor and cruise control box in the engine bay. What does it do?

They are definitely "Bosch Type" relays, but so far I'm damned if I can find out what they're for. Everything I look up is in the junction/fuse box ahead of the washer tank... headbutt

Got it!!

Starting from the passenger side, the first one is the main Cooling Fan relay. The 2 Fan speed-control relays are in the front fuse box...

The other 2 firewall relays are the Main and Pump relays for the ABS system.

That's just a main electrical connector-block, C102.

btw, that's a strut-tower brace, right? What kind?

my mistake, yes a strut tower brace. Its the one for the cadillac CTS. Cheap, quick mod. Takes a little modifying on my 96. Noticeable handling improvement for the price. Though these boats will always handle like boats.
