Where is smg relay on my 645 conv.

There seems to be some confusing data on where the smg relay is on my convertible . Given all the expertise out here...you can share with me where it is. Is it underneath the passenger side filter housing ...or there are two salmon coloured ones in the trunk as well. What are they for?

Any help welcome

I think the relay you are looking for is in the very rear of the glove box. There is also one in the main control box under the hood on the passenger side. Try searching SMG relays, to read past threads. Below is a link to WDS, which will help you locate the relay you are looking for. Java will have to be properly configured to get it to operate properly.

Most have had that salmon colored relay under the passenger filter in the ECU box. But there was one person who had it in the trunk. So if you are having problems with that relay it may be process of elimination.

Hi, I'm just curious as to why you need to know where this relay is? Is there a fault that you have?

Yes one under hood in passenger side and there are also two same colour in the trunk.

Replaced one under hood and car now wont start, cranks but wont start. At first it barely started and died out soon (few seconds) , then wont start at all. I can smell something like some sort if emissions.

Oh crap!

Have you checked your IVM since you have been working under the hood on the main fuse panel? Has the negative cable been pulled on while removing it from the battery? Is the fuel pump supplying fuel to the injectors? Has the car been towed, & possibly set off the anti-theft system? Last but not least, have you measured the voltage at the battery & under the hood? Any of these items can keep the engine from running.
