Okay, I just picked up a 99 Civic Ex with a b18b1 swap in it. I'm trying to figure out what I need to do to get the speedo going. None of the speedo, trip, or odometer work. What I need to know is what I got to do to at least get the speedo going. If anyone can help me out, I'd greatly appreciate it. Thanks in advance...

 

CEL on?

 

There's no CEL... I found out that when they did the swap, they didn't wire up the speedo, so I'm trying to figure out how to wire it up... I'm completely lost in this area of wiring... lol... I just need my speedo back...

 

Why would u need to wire up the speedo? I must be missing something but, i have the same swap and i didnt have to wire anything. If u have no CEL im thinking your gauge is bad? Unless it was coverted to OBD1?

 

It's an obd2a... here's the link to the guy's original ad... He told me something about the VSS being a 3 wire and the clip from the wiring harness is a 4 wire? Idk wtf he's talking about. I'm just trying to figure it out man... Has the swap straight out of the integra, but he said something wasn't right... here's the ad copy and paste this: http://kcsr.org/showthread.php?t=24937

 

there's something about it being something in the ECU that needs to be switched or something... I'm still trying to figure it out...

 

I dunno because those OBD2b cars are a ****ing pain in the ***. The VSS is actually 3 wires on OBD2 so you would need a 3 wire VSS.

 

just go through all your wiring

 

^^^^ exactly just get a 3 wire vss for b series and your set

 

what b series had a 3 wire VSS? that's where I'm stuck right now... figured I'd try and figure it out but I'm having a hard time fellas... I looked today, and I believe the vss is plugged in... I'm not sure if it's the right one or not. I'm so f(_)ckin lost...

 

dunno i guess the OBD2 ones? I know that OBD2 D series have 3 Wire VSS

 

Well, I'm thinkin that I need a 4 wire vss... I'm hearing that the 99 ex had a four wire plug for the gauges and what not. Basically everything works, just not the speedo... So, I'm thinkin it's needing a 4 wire and only has a 3 wire in it...

 

ive never even seen a 4 wire VSS so good luck with that one. All the ones ive seen have the same plugs and it either has 2 or 3 wires going into the plug. And the standard plug only has 3 terminals anyway.

 

Is there anyway that someone might be able to give me some direction as to what to check for. I'm totally lost and about 2 steps away from taking this thing to a shop... I just found out about the 4 wire not being a choice also... I'm ****ing stuck... so it's either a 2 wire or a 3 wire problem... Does anyone have any idea what each colored wire is for? I know the black is for the ground... and that's where I'm lost...

 

Trace the Blu/Wht wire in the VSS connector that runs to the cluster/speedo. If this wire and its terminal in the cluster connector are intact (have continuity and no short), then the cluster is likely bad.

 

So, in theory, I could rewire the vss... right? I could wire it to the vss, then the ecu, then the gauges right? Just basically T it off to the ECU then up to the gauges if I'm reading this right... I might try it tomorrow...

 

As you don't have a VSS code, the Blu/Wht wire between the VSS and ECU is fine. Concentrate on the portion of the wire unique to the cluster.

 

basically, the wire t's off somewhere to go to the ECU... Am I reading that schematic right? So, I guess my main question now is, what all do I need to test for and how do I do it??? I can do pretty much anything else, but when it comes to this previously swapped ****, I have no clue...

 

Unplug the VSS and cluster connector B and check for lack of continuity or a short on the Blu/Wht wire between the two connectors. This wire pins to B11 in the cluster connector.

 

okay, this might be a dumb question, but how do I test for lack of continuity... LIke what do I put the voltmeter on man... You're helpin me a bunch and I appreciate every bit of it man...

 

Continuity tests require a multimeter that measures resistance (Ohms). When you have one, I can tell you how to do the tests for both continuity and a short -- not any more difficult than testing for voltage.

 

I do have a multi meter... It's not with me right now, but I have it in my toolbox at my mom's... I just need to be able to figure it out whenever I get the multi meter here... I have an idea, just not the know how lol...

 

Set the digital multimeter to measure resistance on the lowest scale. For example, if the meter offers 20K, 2K, 200, and 20 Ohm scales, select the 20 Ohm scale.

The tests below are done with both the VSS connector and the cluster connector B unplugged.

Continuity testing: Touch one meter probe to the Blu/Wht wire terminal in the VSS connector and the other meter probe to the Blu/Wht B11 terminal in cluster connector B. Continuity would be indicated by a reading of 1 Ohm or less.

Short testing: Touch one meter probe to the Blu/Wht wire terminal in the VSS connector and the other meter probe to the thermostat housing. A short would be indicated by a low Ohm reading (versus an infinitely high Ohm reading=no short).
