SRS Reset question
Ok, so I've been looking for the Metra model # 72-7802 for the reset but I can't find it because it appears they have discontinued it. Could I use the Metra model # 72-7800 as a replacement?
Here's what reset I'm talking about.. \/

An SCS Service Connector is used to reset your SRS light, which every Honda owner will eventually end up having to do. The dealer charges anywhere from $65 to $95 to do this, I'll show you how to do it for under $10.00. First you need to go to Best Buy or Circuit City and pick up some late model Honda speaker harnesses by Metra. The Metra model number is 72-7802. Cut the female disconnects off the ends of the speaker harnesses and strip about a half inch of jacket off of the wire. Twist the wire together and tape up the bare wire, you now have an SCS Service Connector for quite a but less than what Honda would have charged for one.
Now I'll show you how to reset the light. We've allready done the 1st step by making the SCS Connector.
You'll need to find the MES (Memory Erase Signal) connector.
It is a yellow connector with two wires in it that is plugged into the back of the driver's side fuse box, unplug it and pull it down. Once you have done that you can begin the process of erasing the memory. Here's a diagram for clearer understanding.
1st step in erasing the memory is to turn the ignition off and connect the SCS Service connector to the MES Plug,
2nd Turn Ignition on. SRS indicator light will come on for about 6 seconds then go off.
3rd Disconnect SCS service connector for MES connector within 4 seconds after SRS indicator light goes off. SRS indicator light will come on again.
4th Reconnect SCS service connector the MES connector within 4 seconds after SRS light comes on. SRS indicator light will go off.
5th Disconnect SCS service connector from MES connector within 4 seconds. SRS indicator light will indicate that memory is erased by blinking 2 times.
6th Turn ignition off, and wait 10 seconds. Start vehicle like normal and light should come on and go out like normal. You have reset your SRS light, congrats.
It worked first time for me. If it doesn't work first time, try again. The timing has to be pretty precise. Doing it with the connector I made is much easier that using a paper clip to jump the connector. Good Luck

Re: SRS Reset question
Thanks Muffin but that reference only works if I want to bypass the driver's side, which I might have to end up doing if I can't reset/fix my srs.
What I'm trying to actually accomplish is to reset it because the light came on after setting up my amp & sub and I might have shorted the lines and coincidentally damaged the srs module. I bought a used non-accident one and I hooked up the wires but the light still stayed on.. I thought it's probably still stored in the ECU and I just need to reset it via the referenced reset method above.
Just wanted to know if the 72-7800 would be able to accomplish the same as the 72*-7802 harness for the DIY SCS connection

I have the reset procedure in there as well which worked for my 96 Accord. I had the SRS light on, used a spare piece of wire and inserted it into that plug and followed the reset procedure.
Re: SRS Reset question
Dammit, no I don't have that picture handy 
I deleted it not too long after making that thread - I will double check my camera and can take a look at my 97 Accord to find the same location though.
