I have a new bosche fise box coming for my new p38, and have a few qiestions.

1st, the RL6 and RL7 relays... mine have been swapped with aftermarket relays. I intend to replace those with new ones as I dont know these are correct, I would rather upgrade to the next amperage up from what its supposed to have. Anyone have the OEM part number so I can get the correct relays?

2nd, other than having the key in pocket and the window down, is there anything else I need to prep for when removing the fuse box?

Thanks!

Caution
It would be prudent to call the dealer and buy a whole set of relays to populate the new fuse box you are buying. These relays and the box itself are prone to high heat degradation and could quite feasibly burn up prematurely the printed circuit inside the fuse box.

When replacing the fuse box DISCONNECT the battery negative cable. Remember wires have smoke built into them, bigger the cable or voltage more the smoke that comes out!

The fuse box is in and the p38 now has functioning blower motors and a/c... Unfortunately there is still book on the screen, so im sure I have a blend door issue. Also I think I need fresh relays for the seat heaters as there was some signs of coolant spillage on the underside of the two relays.
