I burned the connector off my OEM unit by hooking the ground up wrong after cleaning and doing maintenance on my 4 Deep Cycle 6V RV house batteries. All a week before leaving for the winter in Florida. I found the information required to ascertain just what the part was I destroyed from an on line site called IRV2. I was delighted to order the part on line and have it arrive in about 4 days, in time to install before I hit the road. An excellent experience after my making a stupid mistake.
