I am rebuilding a 1995 Honda DX 1.5L 16 Valve. When I pulled the head I accidentally broke a two prong connector that is located right under the distributor. The head side of the connector is still attached but the car's side is gone and the two wires are just hanging out. I cannot find that side of the connector anywhere in my engine bay. I need to know the part number and where to order one from. See attached pictures. I also noticed while in the engine bay that there is a ground wire that is not hooked up and was just sitting there attached only on one side on the front top right side of the engine bay area

Head side of the connector.

Two wires that are missing the connector I need.

Grounding strap that is hooked to the car right behind the driver's side headlight.
. Once again see image. Can someone please tell me where this grounding cable is supposed to go? I know this is not the awesome engine that most are working on but this was a $200 project car for me and my 10 year old son to work on for fun. Any help would be greatly appreciated.

 

The connector you broke is the ECT sensor and is critical to the engine running as it tells the ECU the coolant temperature which controls where on the fuel map the engine is.

The grounding strap goes to the power steering bracket on the motor. There is a little 10mm head bolt that is on the top of the bracket.

 

Thank you so much for your help. When looking up the ECT Sensor I can only find the actual sensor that screws into the head. I'm having a hard time finding the car's side of the connector.

 

If you are thinking you can get the connector from Honda, you won't be able to. They only sell full harnesses. That would be the engine harness.

You can either go to the wreckers and cut one out and then since you still have the spades and the seal plug, you could work out the spades from the wrecker one and put it on your harness.

@spAdam posted up some sites you can buy connectors we find on our harness brand new here (post #4 and #8):

And a really good guide to our connectors can be found here:

It's a Sumitomo HW Series sealed connector. 6189-0156. Same connector is on the IACV, Fan Switch, and something else I'm likely forgetting (VTEC pressure switch?)

You need the 20-22 AWG terminals.

You need to get yourself a good "F" type open barrel crimper to do those terminals reliably, the one I usually recommend used to be ~$25 on Amazon but is now $60 for some reason. Message someone at the link I provided and ask them what they recommend for a budget crimper these days, I promise once you'll use it again so it's worth spending a little money on.

 

The crimper I bought and use is 28 on amazon.com


It's been very good to me and I like it a lot. You can change the head out to be for butt connectors, spades, and even our wire harness double crimp connectors. Tight crimp on wire and looser crimp on wire insulation. It's pretty decent quality without the extra dollars.

 

That set looks like it should do nicely.

 

Thank you!!!!!!!!!!!!!!!!!

 

You’re welcome, good luck.

 

Okay so I got the new connector and I went ahead and ordered a sensor set for that line as well. I installed the sensor that goes in the head. But where does this other senor go? Also when I install the new connector on the harness, How do I know which pin goes into which hole? It's only a fifty fifty chance , but I would rather not have to try and swap the pins the connector if I don't have to I'm pretty sure the conector


.

 

That goes on the thermostat housing and it makes no difference what the order of the wires are... the switch closes and this sends a ground to the Cooling fan relay.

 

Once again thank y'all very much.

 

It's the ECT sensor, not the fan switch. But yeah, polarity doesn't matter, it's just a thermistor.

To be correct to the original wiring, the signal should go in pin 1 (closest to the latch) and the sensor ground goes into pin 2.

 

Are you sure ? It certainly appears to be the shape of the fan switch found in the Thermostat housing. All of the ECT sensors that I have seen have a narrower threaded end and a long "thermistor" tip that extends into the head for a proper reading.

 

I agree with JRCivic. Thermostat housing has the flat face.

Here are two ECT sensors I've pulled from my motors, one a D16Z6 and the other a D15B7 (OP's motor).





ECT has a black plastic plug housing, the thermostat housing fan switch has the brown plug housing and the flat face.

Also note the smaller thread diameter. The ECT has a smaller hole that is in the head compared to the fan switch hole in the thermostat housing. Not by much but a bit.

 

Oh you’re right, I didn’t even look at the sensor itself. OP asked about the one under the distributor, which is the ECT. The pictured sensor is a fan switch.

 

The connector that I had to replace was for the temp sensor going into the head. The other sensor that I pictured above was for the thermostat housing. Thankfully I went ahead and bought a new thermostat and gasket since I was going to be working in that area today anyways. I had noticed the previous owner had jumped a wire from the battery straight to than radiator fan. I believe he did that because of the connector I had to replace on the wiring harness to the head sensor was missing and because he was apparently to cheap to buy a thermostat and gasket. Look what I found when I opened the housing up. He just had the shell of the thermostat and a hole lot of gasket sealer in the housing. Who does that!!??? A cheap thermostat is like $7 LMAO. I've been finding things all over this car that has me scratching my head but this one tops them all.

 

No thermostat and a hot wired fan? That thing must have taken forever to get up to temp. I’m willing to bet you’ll be getting better mileage out of it now.

 

My thoughts exactly.
