That'll be fine. After that test make sure power is going to the ICM. Set the meter for 12 volts DC then place the positive (red) lead on the pink/black wire going to the ICM & the negative lead on the battery while key is in the run position. There is a bolt holding the wiring harness into the ICM.

You always want to use a higher setting than what your measuring. Looks like it'll be 25 volts DC on your meter.

Edit - oops - make that 50 volts DC

OK i gave it a whirl and there seems to be no power to the icm but i did not see those specific colors pink/black i did see yellow and i put the negitive to the negitive on the battery. no movement in the tester, i also noticed that the ground cable from the battery to the block was frayed open.

Let'* make sure the meter is set correctly. Just check the battery & see if the meter is showing 12 volts.
