What is this plug for ? (pic inside)
Hey guys, im new into hondas and im learing slowly but I was looking near the ecu and I saw this plug. On the left side there is a paper clip thats in between the wires. On the right side the plug was unplugged so I plugged it back in. I have no idea what those are for or what they do. looks like those wires were tapped into the harness but not sure. If someone can help me out and explain that be great! thanks

2 wire plug is used for checking CELs and also must be jumped when setting the ignition timing. The other one IIRC is for honda diagnostic equipment.

so should I leave both of those plugs connected in ? and also leave the paper clip in ?
Also my del sol has no check engine light. I looked into the cluster and theres a bulb and everything but it never lights up. I have a p28 ecu i dunoo if that makes any difference ? thanks for all the help

I can't remember for sure, but i seem to recall that if the paperclip is in, and there is no stored code then the CEL wont light at all, either that or it stays on solid, I can't remember anymore. Other than that see if the bulb is burnt out. the light should come on when you turn the key on and stay on for about 5 seconds.

How do you know the bulb is fine? Swap it with another bulb from the cluster, and ck again, just for kicks..
Or test the socket with a volt meter, and a third hand turning the key to see if its getting power?
if not, check all fuses
Also, did this car have a swap.. thats the only other cause i see (besides broken wires) thats not an ECU going bad.. But I didn't look very far..
Good luck!

remove the paperclip. turn the ignition to on, the CEL should come on for 2 seconds then turn off.
if this doesnt happen then start troubleshooting. im almost positive the paperclip is preventing the CEL from coming on though
