Got myself one of the MSD radiator fan looms for my 3 door. I'm no auto electrician but it all looks pretty straight forward. One thing I'm not sure about is the original fuse location. Under the cover of the fuse box it looks as though there are two fuses with fan symbols, one noted as number 4 (30A) and number 20 (25A). Does anyone know which one of these I need to pull, or is it both? The instructions don't mention having to remove a relay, is there a relay I'm suppose to take out as well?
Here are the two fuses in question:

One is probably the heater motor, so remove it and see if your blower stops working...
As you have rewired then there is no need to keep any remants of the old loom, the relay will be one of the yellow ones.
