Code reader connection for 1994 villager

Could someone tell me were the location of the code reader connection for the 1994 Villager is? I have looked everywhere that I can think of and the code reader that I have is not giving the information that I need to locate it!!!

I could not post the picture - if you send me a message with your email - I'll send you the pictures that go with the info. below.
I just have it on my computer now - don't know which site I got it from any more. JDW

The Check Engine Light (CEL) codes can be obtained without a trip to the shop or dealer, & without an expensive code reader. The Haynes manual for Mercury Villager/Nissan Quest covers this on page 6-4. To extract the stored codes:
1. Turn the ignition off
2. Unplug the diagnostic plug nearest the starter solenoid
3. Turn the ignition on but don't start the engine
4. Reference this diagram to determine which pins to jumper
5. Plug the jumper wire into the indicated pins in the plug & socket for exactly 2 seconds, no more, no less, and remove the jumper wire
6. The CEL should start blinking, a series of long flashes followed by a series of short flashes. It will repeat the cycle so don't worry about rushing back to the cockpit to get the codes. When the flash sequence repeats, count the number of blinks for the longer duration flashes, & count the number of blinks for the shorter flashes. This will give you the code, for example 12 long flashes followed by 5 short flashes is fault code "1205" which is the transmission "Line Pressure Solenoid" and/or circuit fault (96 & newer).

1993-1995 OBD-I fault codes:
1st digit = number long flashes & 2nd digit = number of short flashes
11 Camshaft position sensor (CMP) or circuit fault
12 Mass air flow sensor (MAF) " "
13 Engine coolant temp sensor (ECT)
14 Vehicle speed sensor (VSS)
21* Ignition signal fault
31 Powertrain control module (PCM)
32 EGR control solenoid
33* O2 sensor
34* Knock sensor (KS)
35 EGR temp sensor (EGRT)
43 Throttle position sensor (TPS)
45 Fuel injector leak
51 Fuel injector signal fault
55* No faults, system normal
* indicates CEL doesn't illuminate but stored fault code can still be retrieved
