Question About Ecu

[Iovko]

Hi! I have question about my avensis. It's T25 1AD-FTV engine, year- 2007 . I'm trying to install cruise control. I musst make connection between the ECU and the seral cable on steering wheel . This is my ECU , but it's different from the corrola and avensis t27 . Pin 23 is for the cruise control , but I don't have Wiring Diagram for my avensis . I have only for Corolla and for the ECU they are 2 sockets - A50 and B31 . By me , they are 4 sockets . Why are they different , but the cars are with same engine ? Here is one picture on avensis t27 ECU - the same like corolla's. . I'm sorry for my bad English.

Here's a better diagram.

Hi Lovko.

Have a look at my latest post ref fitting cruise control. It looks like you have more wires going to connector E10 (top one in your photo) on the ecu than mine. If there is a white wire going to pin 24, you should be good to go. Cruise control switch will plug into pins 8 & 9 on the squib of the steering wheel. Hope this helps.

Hi Lovko.

I had a good look at your picture of your ecu. Connector E10 is actually the second one from the top (not the top one as I said earlier). There is no white wire on pin 24, so retro cruise control will not work in your car either.
