1998 Expy Heater Core Replacement

[Robsan5]

Hey All,
Just replaced the leaky heater core.
Total PITA to remove and replace the dash, of course.
One tip: just cut the metal tubes on the core, then you can access the heater hoses from the engine side of the firewall. This makes it much easier to replace the O-rings inside the connectors. Then coat the O-rings and new heater core tube ends with dielectric grease, this helps to ease the install of the fittings.
But here's my problem-
I can't remember where these two electric connectors go!
They are located near the top of the dash, on the right side of the instrument cluster. I get the feeling I've got to pull the dash back out...
Any help would be awesome...
Thanks,
Robert S

possibly could be for the transfer case shift relays and
torque on demand relays

Hey All,
I figured it out, I had removed the two junctions that those plugs go to,
Thanks for letting me post here.
