latched on/off relay not working properly

https://www.the12volt.com/12voltimages/latchonoffsp.gif Assembled this as the diagram stated to. Verified all wiring then went and installed it in my car to manually toggle the Torque Converter Clutch on and off with a momentary button. Starts open, and turns on when you push the button. But once it is on it won't turn back off. If you push the button you can hear the relays click each time but it will not toggle off after it has been turned on. What's wrong here?

Here is a picture. Relay #1 is on the far right in this photo and relay #4 on the far left. I did make one modification and that was to install a toggle switch to bypass the relays and provide constant 12V if needed however I verified this was not the cause by de-soldering all wires going to the switch and the relay cluster still behaved the same way. It's going to be pretty difficult if not impossible for you trace the connections since a) I only used red and black wire and b) to keep the footprint as small as possible I did not do any splicing and instead opted to solder all spliced wires directly to their associated contacts IE for the momentary switch, instead of the grounding side being spliced into the ground wire, It's soldered directly to contact 86 of relay #2. I also think this may be the reason It's not functioning correctly. I verified all connections 3 times and although everything checks out maybe the contact soldering instead of wire splicing is creating a short since electricity likes to take the path of least resistance?

And the first lesson which you will now always remember is:- Shrink sleeving on diodes, as in all the P's. Doesn't matter if you use the same two colours, something I would never do, as long as you know it. Mr. I didn't spot it because he now rides a uni-cycle and his eyes have gone funny.

The lead is actually not touching. It's just the angle the photo that makes it look that way.

The other thing I noticed is that you do not have a diode across the coil of relay #2. Beyond that, it is difficult to follow each lead in your photo. I know you said you checked the wiring more than once, but I'd go over each connection again and verify each relay is working properly independant of the others. the12volt • Support the12volt.com

If the lead isn't touching but it's close..... Always think of the worst scenario, especially when exposed to the weather. Mount relays terminals down, this will let gravity help the electromechanical movement AND allow any moisture to escape. Don't solder, relays might fail. If anything use a water proof box to IP68 in which to mount the relays. Thoroughly spray with a moisture retarder as you should do on hood pin switches.
