I am working on a 2002 Dodge 2500 and it requires a negative trigger thru 820ohm for lock and a 330ohm resister for unlock. my question is does it matter if the resister is like 335ohm or like 225ohm for unlock or does it have to be 330ohm and same for the lock... I am having some really issues with this truck if anyone has any help here it would be apprectiated..

Usually 10% more or less is normal, but U need a GOOD ground, so U may have to use Relays
