Fuses 32-35 can be found on the rear of this SAM unit.

Expansion slots R1-R4 are switched with the ignition.

Expansion slots R5-R9 are constant live slots. You may find that R9 is occupied with a 25A fuse. This is the power to the heated seats, if you have them.

NOTE: We have found errors manuals with part numbers: Q001 8318 V001 0000 00 and Q002 2074 V001 0000 00. Whenever replacing fuses, do so with one of the same rating. Never put a fuse in of higher rating, unless you know what you are doing.
