Picked up another celica today! However it needs work...a lot of work. I am trying to get this one running and make it my daily driver so I can prepare the 95 vert for the 3sgte swap.
Anyways, here is the story behind this celica...apparently the engine was sputtering over 45MPH so this lady was having her (crazy) fiance work on it. Things ended badly and he didnt want her driving the car so he unplugged and did god knows what to every wire in the engine. I will try to post pictures tomorrow. I am familiar with 5s engine, but the 7A seems foreign to me. The celica is a 1994 GT the 7a, however the engine was replaced with a 1996 7a engine and tranny. I tried starting it today, but the starter would not engaged. The lady stated it had started before. This post has been edited by m2736185: Feb 20, 2012 - 9:42 PM |

Yes, the ECU is going to be changed, but it wont do any good until I can make sense of this wiring.
I wish the previous owner would have left the 4age in there. Anyways I think the reason I dont see a few of the connectors is...the harness has been cut. I have been unable to locate the MAP sensor, o2 sensor, sensor on tranny and a few others. Here is a pic if anyone can identify this part.
