ihatejoefitz Posted March 30, 2005 Share Posted March 30, 2005 do anybody have a good reason why i couldnt just connect my relay board to MS this way. Quote Link to comment Share on other sites More sharing options...
mobythevan Posted March 30, 2005 Share Posted March 30, 2005 That is what I am doing on the TPI megasquirt install. I ordered a DB37 gender changer and just used it instead of builkding a cable. I will be mounting both the ECU and realy board in the same spot. I did verify on the gender changer that all signals were connected. It is working for me.

ihatejoefitz Posted March 30, 2005 Author Share Posted March 30, 2005 why doesnt everybody do this then? it is rediculously easier than making a pigtail. Quote Link to comment Share on other sites More sharing options...
Tony D Posted April 1, 2005 Share Posted April 1, 2005 The relay box is set up for engine room usage, the MS is not. Had my interconenct sensor cables been long enough I suppose I could have moved that into the kick panel also, but one way or the other you will have to make a harness longer. So either your sensor harnesses are longer, or the pigtail moves you remote. Not everyone is installing these in Z's. A VW Bus would be better served with the ECU up front, where you can monitor it, hook up to it, smell it burining while the relays are all out back where they need to be. Another thought would be that with a pigtail, it allows you flexibility in routing where stuff goes. The way I wired some stuff, that straight through connector would send some wierd signals to the box from what I did underneath the relay board conecrning power taps for the heated O2 sensor, CSV, etc! Also, remember you will have to run your power wires to the relay board, meaning power wires through the firewall. Quote Link to comment Share on other sites More sharing options...
ihatejoefitz Posted April 4, 2005 Author Share Posted April 4, 2005 i bought the rs-autosport kit and the wires are long enough to make it to the car parked in front of mines engine bay if need be... i just didnt want all of those prongs soldered together because im not that great of a solderer. im curious why your setup would send weird signals from the heated 02?

Tony D Posted April 5, 2005 Share Posted April 5, 2005 because the power source for the heated O2 is jumpered under the board to S1-5 on the Relay board, and if the straightthrough connector was used, the "jumpers" on the board, would feed back to the ECU... I jumped wires from their "Assigned Spots" in the interconnect cable to other spots for the relay board attachments. Hey, it's open arc, right?

ihatejoefitz Posted April 5, 2005 Author Share Posted April 5, 2005 i didnt assemble my board, so do you think i will have this same problem? when i was reading the "how to assemble pigtail" in the megamanual it didnt say anything about jumping wires. thanks, joe Quote Link to comment Share on other sites More sharing options...
jacob80 Posted September 29, 2008 Share Posted September 29, 2008 Is there a case for the relay board? If the board is exposed like that, I would assume one good washing of the engine and I would be screwed! Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted September 29, 2008 Share Posted September 29, 2008 The components on the relay board are fairly weather resistant - not 100% waterproof, but about as water resistant as most other underhood parts. One thing Bowling & Grippo were concerned about with plugging the relay board into the MS directly was vibration damage from having the two PCBs directly connected through a rigid coupling.

BLOZ UP Posted October 5, 2008 Share Posted October 5, 2008 I prefer to skip the relay board altogether... Quote Link to comment Share on other sites More sharing options...
TONY C Posted October 21, 2008 Share Posted October 21, 2008 I prefer to skip the relay board altogether... I started out that way. But the relay board is just too convienant. I made a nice plexi cover that snaps to it too. Just for looks and to help keep out h2o. Quote Link to comment Share on other sites More sharing options...
z-ya Posted October 24, 2008 Share Posted October 24, 2008 I skip the relay board too. It is easy enough to build a harness with relays, then you have complete control over what signals get shielded and which don't. I keep the relays and fuses close to the MS inside the passenger compartment, everything else is sealed that ends up in the engine compartment.

ihatejoefitz Posted October 24, 2008 Author Share Posted October 24, 2008 This thread is ollllld. Haha, I definitely wasn't thinking too clearly when I came up with this idea. The way the gender changer plug (actually, was just a solder cup) works is basically a straight through, while the cable you need to actually make MS work needs to be the opposite, like a mirror image of each solder cup. http://www.bgsoflex.com/mspower/relay-cable.html :dupe: Quote Link to comment Share on other sites More sharing options...

I measured them when they showed up, they do not just go straight through pin to pin. Quote Link to comment Share on other sites More sharing options...

Nismo280zEd Posted November 5, 2008 Share Posted November 5, 2008 why doesnt everybody do this then? it is rediculously easier than making a pigtail. not everybody is running a relay board. I have all my relays wired to where my fuses are for easy replacement/diagnostics. My ECU is in the glovebox. Quote Link to comment Share on other sites More sharing options...
