I'm slowly working on a plan to upgrade my '99 van's "(black box) vehicle control module" to a 2002 safari van "(0411) powertrain control module". to do so involves swapping every wire on the van's 4-connector black box wiring harness over to the 2-connectors that terminate the harness into the 0411 PCM. the harness wire connector ends are the same for both controllers, so by removing the wires from the van's original connectors and plugging them into the newer connectors, the process basically becomes a plug-and-play exercise. it's an elaborate process however, involving about 80 wires. before I commit to the connector repinning, I want to make sure that I already know where every single wire goes. there may or may not be a complete spreadsheet of the correct connector repining floating round on the web; if there is, I don't have it.
the main reason I want to do this is because I am also in the process of converting to a twin electric fan setup, mounted behind an oversize radiator. the 0411 controller seems to be a "go-to" controller for retrofitting into vehicles of my vintage, where more than original capabilities are desired. for whatever reason, the stars aligned here - newer controllers are more difficult to use. in my case an installed, working 0411 should be just what I want because it has the capability to operate twin electric fans automatically, even though the astro/safari never had electric fans from the factory. as I understand it the black box controller does have the capability to operate one fan.
what I have done so far is scan and print the connector pages from the '99 & '02 astro/safari factory service manuals and tried to match up where the van wires would go on the newer connectors. then I rescanned the marked-up pages and will download them here.
the matchup is not complete yet, this is my first shot at it just sitting at a desk using the manual pages, without any hardware in front of me. there are also some matchups I got from a 2002 express van service manual. these scans I'm posting are still crude/unfinished but I wanted to start posting about this, with hopefully an end result that will give anyone else a working hardcopy of correctly repinned connectors. if anyone has already done this and wants to add their results here, by all means please do so.
here's the unfinished marked up pages.......:
scans of the '99 pages with handwritten location of wires on the 0411 connectors :
scans of the 2002 pages with handwritten locations of wires on the '99 connectors :
