I have a spartan summit gti chassis under my tradewinds le. I was lucky enough to get the electrical systems guide for this chassis , its 90 pages long and very detailed. If anyone should need a copy I can try and email it to you. I have some other electrical info. from National and will be glad to share if needed. I'm glad we have a site to share our info. with each other.
