I hve been reading on this site all day about tach installs....everything is working on the tach....and ive tried every wire i could...even the ignition coil...which was the only one with results....but it redlined at 1100 or so....this is a 1997 x3 and i just have questions on the "WHITE" wire aka pin 47 you guys are talking about...i tried every single white wire....even the multi colored ones with white in them.....i have no set harness coming off my ecu which is confusing...but instead there are about 5 different harnesses that hook up to the main wiring of the ecu....idk what to make of this....idk what harness to look at....i would really appreciate some legitamate instructions and not just a simple...."hook it to the white wire" you ppl need to realize that the people that come to these forums are the ppl who dont know what they are doing at all (me being one of them) ....they come here for answers not more questions....and from what i read in your answers.....it just brings up more questions.....ive been trying to hook this damn thing up all day....i would appreciate a real location to hook in this wire....so anyone who has an x3 with an aftermarket tach...plz look to where all the wires hook up plz....

i would really appreciate some legitamate instructions and not just a simple...."hook it to the white wire" you ppl need to realize that the people that come to these forums are the ppl who dont know what they are doing at all (me being one of them) ....they come here for answers not more questions....and from what i read in your answers.....it just brings up more questions.....ive been trying to hook this damn thing up all day....i would appreciate a real location to hook in this wire....so anyone who has an x3 with an aftermarket tach...plz look to where all the wires hook up plz....

I'm sure someone will be willing to help. Just realize, most people don't want to help those who criticize what they do and how they do it...

Simply asking what wire they were talking about and asking for a picture or diagram would have been nice.

like i said...people have already tried that and all they got was the answer of the white wire pin 47....and as i noticed....there are no pin 47's on my car....let alone and way of organizing wires....theres my ecu....and a big mess of wires coming out of the side of it and split into about 5 sifferent wire clips ......now if you want me to ask questions.....Which wire clip do i look at? and what color of wire is it on that clip....if you say white wire....there is about a 1/30 chance of getting it right....and well...my chances are 1 in a million because ive tried every white wire.

lol...what a mess!


ill go snap a picture of my setup....

there is a pin/wire 47, your just not looking in the right place..

 

[Platinum6316]

OK ... try pin 6 ... sb a Lt Grn w/ Yel stripe.
That is the one shown for Engine Speed.

There is also one that is LT Grn w/ WHI stripe ... DO NOT USE this one ... it's for one of the injectors.

I know it's confusing, but be slow and careful, and you should get it.
So ... on the ECM unit itself, there's a huge connector ...

Along the top row, there's a black wire at #2, so continue counting from there to 6 ... there's also a black wire at 10 ...

Hope this helps.

where the pin rows start is a number. count over to find the one you are looking for

it is a pain...

 

[minorglitch215]

i found this at HMAservice.com for your car. 1997 accent.

 

[caboose826]

your picture actually helped....but i cant find a connector coming righ tout of the ecu....theres the metal box and then a mess of wires coming out of it that split off into multiple connectors....a blue one a white one and a yellow one...and each of those has wires on it....so im still lost as to where this main connector is.....and this mess is all under the driver side dash ....FYI

 

[caboose826]

so what color of wire am i actually looking for?

 

[caboose826]

i finally found that there was a black cover attached to my ecu ....which kept me from seeing the main wire harness.....so i removed it and now im at the same place that your picture shows....with all those same wires....i found one number on that harness and its 56....and its at the bottom row....still cant find 47 and still dont know what color....if im looking for a white wire...i found the only solid white wire in there and spliced into it and got nothing.....so what color exactly is the wire....and what row and everything is it in....because i cant see the right side of the harness

 

[minorglitch215]

there. this is what you are looking for. the actual "pin 47" isnt labeled. you have to count over to it.

DONE.

 

[caboose826]

alright so i was looking at the harness all wrong.... it seems that the 47 is in the middle of all the wires....so im gunna have to dig a little bit... it saids light green and yellow ( white) what exactly does that mean....is the wire yellow and green or white.....just let me know

 

[minorglitch215]

it means that when you count over to pin 47 the wire could be either light green/yellow or it could be white.....


just splice into wire 47 and see...........

 

[caboose826]

i found the wire....but it idles at like 300 rpms and redlines at like 1100....and the tach is set to 4 cylinders....so idk whats wrong

 

[caboose826]

It turned out that my pin 47 was actually solid green.....and i made sure it was pin 47...so idk whats up with my low rpms...

 

[^scythe^]

Probably the return for the tach signal...

[caboose826]

i just dont know why its only registering me for redlining at 1200 and at like 200....its weird...

 

[^scythe^]

Did you splice into #44??
'Cause the RPM signal wire is light green on yellow wire, not solid green...
Take a photo for us...
How quickly does it reach the 1200 'redline'...

that diagram and chart is straight off Hyundai Service Technology.... i remember when i was hooking mine up i hit one of those where i reved it and it would barely go anywhere, but then i found the right one and viola!

 

[caboose826]

so i had it hooked into wqire 44....but in wire 44 i was getting a signal....after the green one there was a brwon and then a blue and yellow then no wire...then a solid white wire....i hooked it into the white wire and nothing happened at all....idk its confusing haha
