<p>[QUOTE=&quot;AModelCat, post: 12198308, member: 167097&quot;]Pretty much. I used truck frame simply because that&#039;s where the battery group is usually grounded. I&#039;d stick with using whatever location your truck already uses for a ground and just put the switch between there and the battery.</p><p><br /></p><p>I&#039;ve also been told that if the ECM is connected directly to the battery terminals that they should be relocated to the other side of the disconnect switch so that the ECM gets disconnected as well. Apparently if you accidently try and crank the engine with the switch off it could cause the ECM to get spiked if its not been isolated.[/QUOTE]</p><p><br /></p>
