gen1lover Posted October 28, 2005 Share Posted October 28, 2005 I have acquired two 93 Legacy sedans. I am going to make one good one out of the two. The one with the good body needs an engine (crankshaft pulley issue) and is not an AWD. The donor car is an AWD. I am thinking of converting the FWD to AWD. My question is what controls the AWD system? I read about Legacy777's conversion and didn't see anything about a computer or anything. Would I also need the engine control module and the trans control module from the AWD car? They are both auto trans. Quote Link to comment Share on other sites More sharing options...

I seem to remeber earlier models it was just easier to find a AWD car and fix it then convert it. Newer ones it looks like its possible but again alot of part work... i can be wrong. nipper Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted October 29, 2005 Share Posted October 29, 2005 I went from auto to manual, and since the MT doesn't use a trans computer, I just got rid of the TCU. For your situation, you would just have to verify the extra wiring is there for the AWD solenoids, etc. If the wiring is there, you'd just have to find an AWD TCU. If the wiring is not there, that will definitely make things a little more difficult, but not impossible. You'd just have to run the extra wires to the TCU.

gen1lover Posted October 31, 2005 Author Share Posted October 31, 2005 So the TCU controls the AWD solenoids? By wiring do you mean extra pins in the connectors? Sorry for all the questions:drunk: Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted October 31, 2005 Share Posted October 31, 2005 Yes to both your questions. Yeah, make sure the pins are there on the connector. Quote Link to comment Share on other sites More sharing options...

oregonloyale Posted October 31, 2005 Share Posted October 31, 2005 you wanna sell the Idle air control valve out of the manual engine? Quote Link to comment Share on other sites More sharing options...
gen1lover Posted October 31, 2005 Author Share Posted October 31, 2005 Sorry, both cars are auto trans. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted October 31, 2005 Share Posted October 31, 2005 Totally unrelated question: What controls the AWD on a manual Trans? A viscous coupling attached to the center differential. Quote Link to comment Share on other sites More sharing options...
