Hello I am having a little trouble with locating where some plugs on my rywire made harness go. Below is a pic of a connector that I just cannot find a spot to plug into. Any Ideas?





Also here is the battery ground and I dont remember where the large eyelet goes sith the rubber boot on it. heres a pic.





I found where this plugs in I was just curious what it is for it was labled by rywire as tw. It looks similar to a coolant temp sensor.





Well while im at it. How about the small sensor the third to the left. Any ideas what it's for?



Sorry for all the questions I bout alldata diy but it didnt help too much. Thanks

 

correction. On the last one its the one to the left of the coolant hose

 

well first off you're in the wrong section, this is the eg,ej,ek section 92-00. your car is a 91 therefore you should of put this in the crx/civic ed/ef section.

That 4 wire plug is for your 4-wire o2 sensor.

The harness you said is for your battery ground is actually for your battery positive. the covered eyelet goes to the starter, and the other wire goes to the fusebox.

the 2 pin black plug that is to the right of the coolant hose is the engine coolant temperature (ECT) sensor. it gives the ecu the reading for your engines temp. the 1 wire connector to the left of the coolant hose is the engine coolant temperature sending unit. this tells the temp gauge on your cluster what to read.

 

Oh.. oops. wrong section toad will take care of that. Del sol's have b16a's so that's why I chose this forum. I should've known that was the o2 sensor. And as far as confusing the pos and neg. I dont wanna talk about it. Any one know what the connecter labled tw stands for? A pic of the sensor is directly above it.

 

It fits on the ect but the label I dont understand.
