Hi guys,

im new here i checked several topics i found on the forums,

but im still not sure if i get it right, my ap1 is equiped with a 4,77 gear ratio. so the speed meter isnt quite correct, i want to buy yellow box to modify that there is a ricks yellow box that says its plug and play, any one knows how to install that "thing" i found modiofry yellow jacket that its doing the same but i think i need to cut cables and its more complicated?

any one can help?

regards

 

I found the manufacturer has the lowest price(use Paypal) on the yellow box: Official home page of the Yellow Box Speedo Recalibrator You can choose from the splice wiring version and the plug N play Version. I received it in about a week and the company replies back to emails quickly also.

 

and this one?

Rick's Yellow Box

 

It's the same product. You save a few dollars buying it from the manufacturer.

 

ok i found a post from a guy showing some pics how to connect and its plug and play it goes where the transmision is.
