[QUOTE=dew1989;2057770]Okay so how do I wire this up lol…i’ve extended the wires, and the plug from the obd1 harness has green/white and red/white wires. Where do my black and yellow/green wires connect :S …
Oh, and so I don’t look like a total idiot, the reason why I couldn’t find the 3 prong TPS plug was the male end was broken off, so I just used the one of my LS[/QUOTE]
Re-read this entire post and all of my responses, it seems as if you’ve extended the wrong wires. Also, do you not have a helms manual? If you do, why aren’t you using it? If you don’t, why haven’t you bought one?
The blk and yel/grn wires are for the ECT switch. These need to be connected to the ECT switch on your thermostat housing. In order to do this you not only need to extend the wires, but solder on a new type of connector (just use the connector off of your obd1 engine harness).
For reference, here is a pic of the thermostat housing from my b17a showing the ECT switch with connector attached. As you can see, wire colors are blk and yel/grn. Those colors are also listed in the Helms.
The engine oil temp switch should have a blk wire and a wht/grn wire. Your OBD0 engine harness should have this connector for this, but there’s a chance you don’t have an engine oil temp switch on your b16a. Different models of cars with different options needed this switch for different things. for instance, USA models w/o AC and CDM models w/ AC did not have this switch. However USA models w/ AC did have the switch.
In THIS photo you can see the Engine Oil Temp switch (it’s to the left of the oil filter and green in color). You’ll notice that it looks basically exactly the same as the OBD1 ECT swtich.
Don’t worry, I didn’t forget about the grn/wht and red/wht wires you mentioned… Sounds like you extended the wires which were for the ECT Sensor. The ECT sensor uses those wire colors (per my experience and confirmed w/ Helms manual).
The ECT sensor is located on the distributor side of the head on both vtec and non-vtec heads. They are in slightly different locations due to the addition of the vtec solenoid, but they’re only a few inches different. The connector used for the ECT Sensor is the same as the OBD1 style ECT Switch.
For reference, here is a photo showing the location of the ECT Sensor on my b17a head. You can see the gray connector directly under the vtec solenoid. IIRC the sensor itself is a white color. Sorry I don’t seem to have a better pic of the sensor unplugged.
