1989 318 TBI ignition questions
Lockup converter on the transmission is a consideration too. They made a lockup type and a non lockup type in those years.
The original automatic to this '90 318 TBI was a non-lockup converter designated by the 2 pin terminal by the shift linkage.
3 pin terminals were for the lockup converters. Some folks have manually switched them for hot rod / non factory setups.
Also as you know 360 is external balanced and the original 318 was internal balanced, so going to need that special notched out flex plate for the 360 setup with automatic.
