13D i dont have connected. 1c i dont have connected. 10b i have connected to 19c which is suppose to be violet. 11b i have connected to 20c which is suppose to be violet w/white. 9d i have connected with 9c. I dont think all the colors were the same as the ones listed on the schematic. For 1 C i had no wires there from the pigtail that i received with the cluster, although the pin next to it was orange, but that pin 2c i had connected with 20a. From the 95 harness i have nothing connected to 13c which is for the vehicle speed sensor

It looks to me like 13D on the cluster should be the speedo signal. 13C from the 95 harness should go to 13D on the cluster from what I can tell.

For the tach, run a dedicated wire from the igniter to pin 9D on the cluster. IIRC, the igniter tach signal wire is pin 1 on the 4 pin plug. It is a small black wire.

I know il test it later today and will post up results. For the outside temp. i have 19D connected with 14b. Both of which are suppose to be green wires. If thats correct and i should be getting a temperature reading then i guess my sensor is shot or something. Thanks stockhatch!

Yea2jz is your cluster on the way? Was it from a 97 or 99? Lets hope the info from stock hatch works so you youll be set before the cluster gets in.

Not yet I am sending Aliga the payment for the cluster tonight, He told me it was exactly like the one he sent you so I am asuming that its a 98+ because on a 97 the "PRND123" part is straight down like a pre 97 but on the 98+ they are some what gated like the shifter and thats what I want

Looks like C14 from the 95 harness should go to it. Is C14 pink?

That I dont know. My early diagram has no provision for outside temp...

Ok, referencing a 95 SC400 cluster diagram, that does sound correct. Not sure why its not working unless its a thermistor with different resistance values or something.

Its cool thanks stockhatch you mind if i buy u a case of beer? Well through paypal of course because my tach and speedometer works now.

yea2jz just use the excel sheet i sent you and put 13d from 99 cluster to 13c 95. For the tach i had to tap the ignitor exactly how stockhatch told me to.
