hey guys i'am ready to run my wires for the ls1 gauge cluster , just got the plug for the back and i dont have a clue what wire do what and go where.

cluster and plug are from a 2000 z28 , can some one help me please

brandon1566

cant answeer ur ? but curious as to why you arent keeping the mustang cluster

never thought of it really, didnt think i could use it with the ls1 sensors or senders

brandon1566

good ? im doing the swap now on an 02, im going to try to use it im sure you can just catch tach wire and theres an adaptor for the t400 im using for the speedo.

iam sure you can , i didnt know if the ls1 pcm uses the sensors for info , more coolant temp then anything.

Here are the pin-outs for the ls1:

Here are the pin outs to the mustang cluster if you want to incorporate them together.

thanks, all i need is rpm gauge, speed, batt, water temp and oil pressure, and found out whats needed to hook up the ls1 fuel level to the ford sender

i dont see what i need, can someone let me know the wires i need. I need the cluster wires and the wires they go to on the pcm.

speed

rpm

oil pressure

water temp

fuel

volts

and if theres a charge light in the cluster that needs to be hooked up

I believe all the ones listed above are provided through the serial data wire/cable EXCEPT the oil pressure which comes straight from the sensor to the cluster on the Fbodies if I remember correctly.

I searched and searched thru all my hot rods, and popular hot rodding, but one of those two did a mustang ls1 swap and the cluster as well, and it was said that the cluster swap was straightforward and helped a bunch. Try their websites.

I would have used the wiring from a F-body and ran it from the connectors and the gauges..

Finally was able to get my instrument cluster to operate via the serial data wire. All the gauges are working except the fuel level which I'm still working on (need to add a pin to PCM which grounds the fuel sender). I took my 3rd gen cluster diagrams and hooked them up to the cluster along with the serial data wire from the LS1 PCM as follows:


3rd gen connectors that go to cluster


Incorporated to 4th gen cluster pin outs as follows:
A3 PNK 39 Ignition Power...to 3rd gen Clear Connenctor #2 or #6 Pnk w/Black

now for the pics.

Why not get a gauge panel from http://www.florida50.com/ and run aftermarket gauges.

does the pcm read the oil pressure sensor, and i only have one coolant temp sensor in the drivers side head[ this is used for the pcm to turn on the fan and stuff right.

might just sell the plug anf cluster and do autometer stuff

crazygn

i'am at a loss, someone help me out here. I need to find these wires on the cluster plug, i have the wires ready on the engine harness.

rpm

speed

water temp

oil pressure

volt

fuel

screaminChick-n

TPI TERR......What if I want to go the other way around. I want to use the 3rd gen gauge cluster.

Ur case u wired the 3rd gen connector to LS1 connector for power , gnd and other stuff that dont come thru the serial data cable.

I am trying to connecto wires from the LS1 gauge connector to the 2 3rd gen conn and use the stock gauge cluster and not the LS1 gauge cluster.

There ya go hope that is what your looking for.

PCM needs the water temp sensor (ECT), that's how the PCM controls the fans, it also needs ECT for fuel calculations... I do not remember exactly, but somewhere along the way, if i'm not mistaken, the ETC became another Class II Data item. If you can get the pin on the cluster, you need to get a 3 wire temp sensor, GM sells them and you can search the p/n. one of the wires is reference, one is for PCM, the other you run to the cluster... You will have to check to see if your 2000 Cluster has a Class II water temp gauge.

In case you hadn't heard this before, the water temp gauge will show more "trends" than anything, if you were to compare the gauge to the reading you get from the PCM (using a scanner) it's not going to be exact (sometimes it's off by 30+ degrees)...Looks like an interesting build!

thanks, i need to set back and write this all down and think about it. I'am going crazy with it and iam sure its not that hard to do.
