Workshop Manuals, general information & Wiring Diagrams

There is a lot of information available across the internet but it can be hard to track down if available at all. What we have done is collect what we can and put it all in one place on here for the convenience of anyone who needs it.


This page contains information and pictures collected from multiple sources, we have given credit where possible, however in all but a small part of the content here it is unknown who the original up loaders/translators/authors where. So while we don't know who any of you are we thank you. If anyone has their something of theirs hosted here and does not wish it to be then please contact us and we will gladly remove it.


NOTE: While the workshop manuals are a sure bet we otherwise can't vouch for the accuracy of the information on this page, it's up to the individual to check and confirm anything shared here.

SIlvertop harness with a Blacktop ECU: [File]

How to convert the wiring harness from a 20V Silvertop to be compatible with that of a Blacktop ECU. This conversion allows for use of a Blacktop MAP sensor in the place of the Silvertop air-flow meter and hence the ability to run an open air intake. Other advantages include raising the rev limit as well as others. This article was originally featured in the Jan 2012 issue of 86Garage magazine and is courtesy of J.Velasco.
