ev button install problem

I have done a lot of reading, but I haven't come accross anyone who has had the same problem I have, so I am just going to ask instead of spending another hour looking for an answer.

I have a 2008 and I am trying to install the Sigma EV button. I got the button to light up so I think that part is ok. In ran the wire over and installed the pin (from the flasher harness) into #27 When I started the car, the "check engine" light was on. I immediately turned it off, checked that I indeed had the pin in #27 and tried again. The light was still on, but I closed the doors and shifted into reverse to try it out anyway. The ICE was already running when I pushed the button. A message came up on the screen that said something like, EV mode can not be engaged now, which is exactly what it should have done since the ICE was running. When I came to a stop light I pushed the button when the ICE wasn't running and no EV light came on up on the dash, but when I drove around for a while, the engine never came on. When I hit 35, the car beeped and the ICE kicked in. The "check engine" light was still on, so I pulled out the pin on the ECU and drove around again. The light was off and the ICE came one where it hadn't before.

I distorted the pin a bit when I crimped the two sharp parts around the wire, but I straightend it and made sure the solder was as smooth as possible. Still, I had a hard time getting the pin in the last milimeter or two. I am not entirely sure I got it in all the way and I don't think the pin lock was all the way down on that side (I pushed on it, but it didn't move). Could that be the cause of the "Check engine" light?

Sorry for the long post, but my wife will kill me if I screw up her car.

Thanks for any help!

 

Bummer! 159 views and no suggestions as to what could be going on here. I accidentally came accross another 2008 owner who had exactly the same issue, but I couldont find out what he did about it. Have any other 2008 owners encountered difficulty? For that matter have any 2008 owners been successful?

Tomorrow I will have time to go out and mess around with it agian. If I can't get it to work with out the "check engine" light though, I am not going to use it.

You guys nailed it. I was listening to the radio when I was running the wires, but then forgot to turn the car off when I plugged it in to the ecu. Immediately after I did it, I couldn't believe my stupidity and I worried that I had damaged the ECU. The car worked perfectly, however, except the light. When I unplugged the EV button, the light went off, so I assumed that was the problem. It works perfectly now though.

I saw on one of the web sites that an EV light actually turned on up on the dash when EV mode is engaged. My car doesn't do that though. Did US cars come without that bulb installed?

Thanks for all your help! We live at the top of a large hill and once at the bottom we enter the freeway, so keeping the ICE off until we get on the on ramp seems to make sense.

Thanks for all your help!!
