his harness is made for a magnum fuel injected engine; it uses a crank sensor which is very hard to mount to an LA series engine as well as the magnum intake which is a different bolt pattern then your LA engine
I however do a TBI kit which is fuel injection as well but only uses two injectors and no crank sensor its made for the LA engine
if you need to retrofit a magnum engine in a older car his is the best choice
if you need to run EFI on a stock or near stock LA engine I can help you there
