It looks like they have a misprint in their list of manuals They list the 10308 as an "18" circuit kit but when you open the link it is indeed your 8 circuit manual. First page for all of their manuals scroll down https://www.painlessperformance.com/wc/manuals.php?s=0 Note: some times the link for the pfd doesn't always open if it is the posted link and it is simpler to post the web page with the list of PFD links. Then you get to sort through and find what you need for the parts and pieces on your engine as they show how to hook up GM, Mopar and or Ford components and some times you have to make sure yhat you are following the directions for what you have and didn't get side tracked.
Good catch there Mr 48! I took some time to look through the manual . It appears that there is enough well written and illustrated instruction there to get the average garage monkey through his wiring project.
painless got back to me and said mine was for a Ls swap. manual looks the same. they have me confused. mine is turn signals and speedway turn signal thanks for input
