I have a 78 FJ40 that needs a new engine (it was previously desmogged with a Holley carb). I have bought a 2F from a 85 FJ60 that I am going to stick in as a replacement. The engine and all the smog equipment work, so ideally I would like to keep it on rather desmogging and having the dissy recurved.
So the question is, has anyone used the 78 wiring harness to control the 85 smog equipment (studying the diagram it looks like the may be challenges or part that may not work correctly). The alternative is to splice in part of the 85 wiring harness to control the VSVs and carb etc. and use the 81 and up emissions controller.
Has anyone done this mod at all? I would ideally like to do it in a way that it can be reversed at a later stage. Looking for a bit of feedback from the experts, thanks in advance.
