ABC Direct Auto Parts

We wanted to update this thread and extend a big THANK YOU to all of you! With your assistance our customers are having a much easier time ordering the correct wires.

Thank you for all of the replies...very very helpful! Do you know if there are any clearance issues (manifolds, A/C lines, etc) with using the added wire length on trucks that are supposed to have the shorter wires?

We are reaching out for some assistance on this topic. We sell ignition wires for the GM LS style engines and one issue that we continue to run into is that most listings list 2 types of wires for each truck depending on the type of coil the truck has. An example of this is: if your truck came with the 19005218 style coil pictured below you would use one wire set. ..and if your truck came with the 12558693 style coil you use a different wire set which is below. The issue is that many customers with the 02-07 trucks do not look into the style of coil that they have and they end up ordering the wrong set. Is there a specific engine for each type of coil or an absolute way to know what style it has based upon the body style? For example would the 6.0L engine only use the 12558693 style coil? We look forward to some of your insight and any assistance you can provide.
