Hi all,

 

Just purchased a ke70 sr20det and the dash isn't working. Its a stock 180sx ecu. Anyone have any ideas?

What do you mean by dash? Do you mean the instrument cluster?

 

Check that it's plugged in.

If it's not lighting up and the clock doesn't work it's not getting power/not plugged in. Otherwise it's not wired up properly and you'll have to go through and connect the wires to the sensors.

The tachometer (if it has one) is meant to work with a distributor setup, it won't work with individual coil packs and you'll need to modify it - there are guides on the internet for this.

The speedo probably isn't working because the speedo cable doesn't fit the Nissan gearbox, if they even use speedo cables? You'll either need to get an adapter/custom cable or use an electric speedo.

The dash isn't working is a vague explanation. Do better if you expect help. Itemise the issues as they will most likely need attention one thing at a time. What is and isnt working.

Also, from a moderators point of view, you will only piss us off if you make multiple threads in multiple places for the same discussion, not to mention it will be counter-productive to the people who try to help you. So please learn some patience and stop making extra threads for the same question. Its the middle of a work day, most people have jobs, so you will have to wait till people have the time to help you.

Sorry guys, newby to the forums.

 

From what I saw I can see the clock is working just not the speedo & tacho not working. I will check the wires at the back of the cluster when I get home.

Ok guys, figured it the speedo cable at the back wasnt plugged in. Plugged it back in and no luck. I googled and found an rb30 speedo cable should work. Can anyone else confirm this?

Is it screwed into the gearbox?

 

You need to install the senders from the original car usually to make the gauges work like the temp gauge and such. Tacho needs to be connected up to your tacho output. From memory a black wire that used to be on the coil and originates in the left kick. Speedo is a worm driven cable. It either is connected or it isnt. The oil pressure warning light (engine light) need to be connected to the oil pressure switch from the original car too. Blinkers and all other native functions should be fine, as will your charge light if your alternator is wired correctly.

 

Its really worth putting a few hours inot making it all work and seem factory, plus it a rwc fail to have dead instruments.

All other inputs in dash are working fine. Clock, blinkers, charge light, oil etc. Just the speedo and tach.

To be honest mate, to allow others a better idea of what you require in assistance can you please take a photo of the ECU serial number, also of the type of dash you have as there are 2 different S13/180sx dashes.

 

Also can you take a pic of the shifter location so that it can be determined if the SR box was used or an RB20 box was used and pic of the speedo sensor as the wiring colours and sender pin outs are different between the models just to make sure is an S13 box not an S14 box.

 

FYI the speedo sensor is located at the rear of the box on the drivers side it has a 3 pin plug, as well the speedo sensor will be the box other wise it will leak gearbox oil everywhere.
